<!-- Entry for CREATE-THREAD -->

<p><br>[Function]<br><a class=none name='create-thread'><b>create-thread</b> <i>fun arg</i> =&gt; <i>result</i></a>
<blockquote><br><pre>

Parameters
fun
      A pointer to a function that acts as the entry point for the new thread. The function should have
      the following C language prototype:
      void GLFWCALL functionname( void *arg );
      Where functionname is the name of the thread function, and arg is the user supplied argument
      (see below).
arg
      An arbitrary argument for the thread. arg will be passed as the argument to the thread function
      pointed to by fun. For instance, arg can point to data that is to be processed by the thread.
Return values
The function returns a thread identification number if the thread was created successfully. This number
is always positive. If the function fails, a negative number is returned.
Description
The function creates a new thread, which executes within the same address space as the calling process.
The thread entry point is specified with the fun argument.
Once the thread function fun returns, the thread dies.
Notes
Even if the function returns a positive thread ID, indicating that the thread was created successfully, the
thread may be unable to execute, for instance if the thread start address is not a valid thread entry point.

<!-- Entry for DISABLE -->

<p><br>[Function]<br><a class=none name='disable'><b>disable</b> <i>token</i> =&gt; <i>result</i></a>
<blockquote><br><pre>

Parameters
token
       A value specifying a feature to enable or disable. Valid tokens are listed in table 3.8.
Return values
none
Description
glfw::Enable is used to enable a certain feature, while glfw::Disable is used to disable it. Below follows a
description of each feature.
+AUTO_POLL_EVENTS+
When +AUTO_POLL_EVENTS+ is enabled, glfw::PollEvents is automatically called each time
that glfw::SwapBuffers is called.
When +AUTO_POLL_EVENTS+ is disabled, calling glfw::SwapBuffers will not result in a call to
glfw::PollEvents. This can be useful if glfw::SwapBuffers needs to be called from within a callback
function, since calling glfw::PollEvents from a callback function is not allowed.
+KEY_REPEAT+
When +KEY_REPEAT+ is enabled, the key and character callback functions are called repeatedly
when a key is held down long enough (according to the system key repeat configuration).
When +KEY_REPEAT+ is disabled, the key and character callback functions are only called once
when a key is pressed (and once when it is released).
+MOUSE_CURSOR+
When +MOUSE_CURSOR+ is enabled, the mouse cursor is visible, and mouse coordinates are
relative to the upper left corner of the client area of the GLFW window. The coordinates are limited to
the client area of the window.
When +MOUSE_CURSOR+ is disabled, the mouse cursor is invisible, and mouse coordinates are
not limited to the drawing area of the window. It is as if the mouse coordinates are recieved directly
from the mouse, without being restricted or manipulated by the windowing system.
+STICKY_KEYS+
When +STICKY_KEYS+ is enabled, keys which are pressed will not be released until they are
physically released and checked with glfw::GetKey. This behavior makes it possible to catch keys that
were pressed and then released again between two calls to glfw::PollEvents, glfw::WaitEvents or
glfw::SwapBuffers, which would otherwise have been reported as released. Care should be taken when
using this mode, since keys that are not checked with glfw::GetKey will never be released. Note also that
enabling +STICKY_KEYS+ does not affect the behavior of the keyboard callback functionality.
When +STICKY_KEYS+ is disabled, the status of a key that is reported by glfwGetKey is always
the physical state of the key. Disabling +STICKY_KEYS+ also clears the sticky information for
all keys.
+STICKY_MOUSE_BUTTONS+
When +STICKY_MOUSE_BUTTONS+ is enabled, mouse buttons that are pressed will not be
released until they are physically released and checked with glfw::GetMouseButton. This behavior
makes it possible to catch mouse buttons which were pressed and then released again between two calls
to glfw::PollEvents, glfw::WaitEvents or glfw::SwapBuffers, which would otherwise have been reported
as released. Care should be taken when using this mode, since mouse buttons that are not checked with
glfw::GetMouseButton will never be released. Note also that enabling
+STICKY_MOUSE_BUTTONS+ does not affect the behavior of the mouse button callback
functionality.
When +STICKY_MOUSE_BUTTONS+ is disabled, the status of a mouse button that is reported
by glfwGetMouseButton is always the physical state of the mouse button. Disabling
+STICKY_MOUSE_BUTTONS+ also clears the sticky information for all mouse buttons.
+SYSTEM_KEYS+
When +SYSTEM_KEYS+ is enabled, pressing standard system key combinations, such as
ALT+TAB under Windows, will give the normal behavior. Note that when ALT+TAB is issued under
Windows in this mode so that the GLFW application is deselected when GLFW is operating in
fullscreen mode, the GLFW application window will be minimized and the video mode will be set to
the original desktop mode. When the GLFW application is re-selected, the video mode will be set to
the GLFW video mode again.
When +SYSTEM_KEYS+ is disabled, pressing standard system key combinations will have no
effect, since those key combinations are blocked by GLFW. This mode can be useful in situations when
the GLFW program must not be interrupted (normally for games in fullscreen mode).

Return values
The function returns t if the extension is supported. Otherwise it returns nil.
Description
The function does a string search in the list of supported OpenGL™ extensions to find if the specified
extension is listed.
Notes
An OpenGL™ context must be created before this function can be called (i.e. an OpenGL™ window
must have been opened with glfw::OpenWindow).
In addition to checking for OpenGL™ extensions, GLFW also checks for extensions in the operating
system “glue API”, such as WGL extensions under Windows and glX extensions under the X Window

Parameters
mode
       Pointer to a GLFWvidmode structure, which will be filled out by the function.
Return values
The GLFWvidmode structure pointed to by mode is filled out with the desktop video mode.
Description
The function returns the desktop video mode in a GLFWvidmode structure. See glfwGetVideoModes
for a definition of the GLFWvidmode structure.
Notes
The color depth of the desktop display is always reported as the number of bits for each individual color
component (red, green and blue), even if the desktop is not using an RGB or RGBA color format. For
instance, an indexed 256 color display may report RedBits = 3, GreenBits = 3 and BlueBits = 2, which
adds up to 8 bits in total.
The desktop video mode is the video mode used by the desktop, not the current video mode (which may
differ from the desktop video mode if the GLFW window is a fullscreen window).

Description
The function returns the OpenGL™ implementation version. This is a convenient function that parses
the version number information from the string returned by calling
glGetString( GL_VERSION ). The OpenGL™ version information can be used to determine
what functionality is supported by the used OpenGL™ implementation.

<blockquote><br><pre>

Parameters
joy
       A joystick identifier, which should be +JOYSTICK_n+ where n is in the range 1 to 16.
numbuttons
       Specifies how many buttons should be returned.
Return values
       A list that will hold the button states for all requested buttons.
The function returns the number of actually returned buttons. This is the minimum of numbuttons and
the number of buttons supported by the joystick. If the joystick is not supported or connected, the
function will return 0 (zero).

Description
The function queries the current state of one or more buttons of a joystick. The button states are
returned in an array, where the first element represents the first button of the joystick. Each state can be
either +PRESS+ or +RELEASE+
If numbuttons exceeds the number of buttons supported by the joystick, or if the joystick is not
available, the unused elements in the buttons array will be set to +RELEASE+

Notes
The joystick state is updated every time the function is called, so there is no need to call glfw::PollEvents
or glfw::WaitEvents for joystick state to be updated.
Use glfw::GetJoystickParam to retrieve joystick capabilities, such as joystick availability and number of
supported buttons.

returned in an array, where the first element represents the first axis of the joystick (normally the X
axis). Each position is in the range -1.0 to 1.0. Where applicable, the positive direction of an axis is
right, forward or up, and the negative direction is left, back or down.
If numaxes exceeds the number of axes supported by the joystick, or if the joystick is not available, the
unused elements in the pos array will be set to 0.0 (zero).

Notes
The joystick state is updated every time the function is called, so there is no need to call glfw::PollEvents
or glfw::WaitEvents for joystick state to be updated.
Use glfw::GetJoystickParam to retrieve joystick capabilities, such as joystick availability and number of
supported axes.
No window has to be opened for joystick input to be valid.

<p><br>[Function]<br><a class=none name='get-key'><b>get-key</b> <i>key</i> =&gt; <i>result</i></a>
<blockquote><br><pre>

Parameters
key
      A keyboard key identifier, which can be either an uppercase printable ISO 8859-1 (Latin 1)
      character (e.g. &#039;A&#039;, &#039;3&#039; or &#039;.&#039;), or a special key identifier. Table 3.3 lists valid special key
      identifiers.
Return values
The function returns +PRESS+ if the key is held down, or +RELEASE+ if the key is not
held down.

Description
The function queries the current state of a specific keyboard key. The physical location of each key
depends on the system keyboard layout setting.

Notes
The constant +KEY_SPACE+ is equal to 32, which is the ISO 8859-1 code for space.
Not all key codes are supported on all systems. Also, while some keys are available on some keyboard
layouts, they may not be available on other keyboard layouts.
For systems that do not distinguish between left and right versions of modifier keys (shift, alt and
control), the left version is used (e.g. +KEY_LSHIFT+)
A window must be opened for the function to have any effect, and glfw::PollEvents, glfw::WaitEvents or
glfw::SwapBuffers must be called before any keyboard events are recorded and reported by
glfw::GetKey.

Parameters
procname
       A null terminated ISO 8859-1 string containing the name of an OpenGL™ extension function.
Return values
The function returns the pointer to the specified OpenGL™ function if it is supported, otherwise
NULL is returned.
Description
The function acquires the pointer to an OpenGL™ extension function. Some (but not all) OpenGL™
extensions define new API functions, which are usually not available through normal linking. It is
therefore necessary to get access to those API functions at runtime.
Notes
An OpenGL™ context must be created before this function can be called (i.e. an OpenGL™ window
must have been opened with glfw::OpenWindow).
Some systems do not support dynamic function pointer retrieval, in which case glfw::GetProcAddress
will always return NULL.

Return values
The function returns different parameters depending on the value of param. Table 3.2 lists valid param
values, and their corresponding return values.

Description
The function is used for acquiring various properties of an opened window.

Notes
+ACCELERATED+ is only supported under Windows. Other systems will always return
GL::+TRUE+. Under Windows, +ACCELERATED+ means that the OpenGL™ renderer is a 3rd

Parameters
data
       The memory buffer holding the contents of the file that should be loaded.
size
       The size, in bytes, of the memory buffer.
flags
       Flags for controlling the texture loading process. Valid flags are listed in table 3.7.
Return values
The function returns t if the texture was loaded successfully. Otherwise nil is
returned.

Description
The function reads an image from the memory buffer specified by the parameter data and uploads the
image to OpenGL™ texture memory (using the glTexImage2D function).
If the +BUILD_MIPMAPS_BIT+ flag is set, all mipmap levels for the loaded texture are
generated and uploaded to texture memory.
Unless the flag +ORIGIN_UL_BIT+ is set, the origin of the texture is the lower left corner of the
loaded image. If the flag +ORIGIN_UL_BIT+ is set, however, the first pixel is the upper left
corner.
For single component images (i.e. gray scale), the texture is uploaded as an alpha mask if the flag
+ALPHA_MAP_BIT+ flag is set, otherwise it is uploaded as a luminance texture.

Notes
glfw::LoadMemoryTexture2D supports the Truevision Targa version 1 file format (.TGA). Supported
pixel formats are: 8-bit gray scale, 8-bit paletted (24/32-bit color), 24-bit true color and 32-bit true color
+ alpha.
Paletted images are translated into true color or true color + alpha pixel formats.
The read texture is always rescaled to the nearest larger 2m × 2n resolution using bilinear interpolation,
if necessary, since OpenGL™ requires textures to have a 2m × 2n resolution.
If the GL_SGIS_generate_mipmap extension, which is usually hardware accelerated, is supported by
the OpenGL™ implementation it will be used for mipmap generation. Otherwise the mipmaps will be
generated by GLFW in software.
Since OpenGL™ 1.0 does not support single component alpha maps, alpha map textures are converted
to RGBA format under OpenGL™ 1.0 when the +ALPHA_MAP_BIT+ flag is set and the loaded
texture is a single component texture. The red, green and blue components are set to 1.0.

<blockquote><br><pre>

width
      The width of the window. If width is zero, it will be calculated as width = 4/3 height, if height is
      not zero. If both width and height are zero, then width will be set to 640.
height
      The height of the window. If height is zero, it will be calculated as height = 3/4 width, if width is
      not zero. If both width and height are zero, then height will be set to 480.
redbits, greenbits, bluebits
      The number of bits to use for each color component of the color buffer (0 means default color
      depth). For instance, setting redbits=5, greenbits=6, and bluebits=5 will generate a 16-bit color
      buffer, if possible.
alphabits
      The number of bits to use for the alpha buffer (0 means no alpha buffer).
depthbits
      The number of bits to use for the depth buffer (0 means no depth buffer).
stencilbits
      The number of bits to use for the stencil buffer (0 means no stencil buffer).
mode
      Selects which type of OpenGL™ window to use. mode can be either +WINDOW+, which
      will generate a normal desktop window, or +FULLSCREEN+ which will generate a
      window which covers the entire screen. When +FULLSCREEN+ is selected, the video
      mode will be changed to the resolution that closest matches the width and height parameters.

Return values
If the function succeeds, t is returned.
If the function fails, nil is returned.

Description
The function opens a window that best matches the parameters given to the function. How well the
resulting window matches the desired window depends mostly on the available hardware and
OpenGL™ drivers. In general, selecting a fullscreen mode has better chances of generating a close
match than does a normal desktop window, since GLFW can freely select from all the available video
modes. A desktop window is normally restricted to the video mode of the desktop.

Notes
For additional control of window properties, see glfw::OpenWindowHint.
In fullscreen mode the mouse cursor is hidden by default, and any system screensavers are prohibited
from starting. In windowed mode the mouse cursor is visible, and screensavers are allowed to start. To
change the visibility of the mouse cursor, use glfwEnable or glfwDisable with the argument
+MOUSE_CURSOR+

target
       Can be any of the constants in the table 3.1.
hint
       An integer giving the value of the corresponding target (see table 3.1).

Description
The function sets additional properties for a window that is to be opened. For a hint to be registered, the
function must be called before calling glfw::OpenWindow. When the glfw::OpenWindow function is
called, any hints that were registered with the glfw::OpenWindowHint function are used for setting the
corresponding window properties, and then all hints are reset to their default values.

Notes
In order to determine the actual properties of an opened window, use glfw::GetWindowParam (after the
window has been opened).
+STEREO+ is a hard constraint. If stereo rendering is requested, but no stereo rendering capable
pixel formats / visuals are available, glfw::OpenWindow will fail.
The +REFRESH_RATE+ property should be used with caution. Most systems have default values
for monitor refresh rates that are optimal for the specific system. Specifying the refresh rate can
override these settings, which can result in suboptimal operation. The monitor may be unable to display
the resulting video signal, or in the worst case it may even be damaged!

Width and Height give the dimensions of the image. Format specifies an OpenGL™ pixel format,
which can be GL_LUMINANCE or GL_ALPHA (for gray scale images), GL_RGB or GL_RGBA.
BytesPerPixel specifies the number of bytes per pixel. Data is a pointer to the actual pixel data.
By default the read image is rescaled to the nearest larger 2m × 2n resolution using bilinear
interpolation, if necessary, which is useful if the image is to be used as an OpenGL™ texture. This
behavior can be disabled by setting the +NO_RESCALE_BIT+ flag.
Unless the flag +ORIGIN_UL_BIT+ is set, the first pixel in img-&gt;Data is the lower left corner of
the image. If the flag +ORIGIN_UL_BIT+ is set, however, the first pixel is the upper left corner.
For single component images (i.e. gray scale), Format is set to GL_ALPHA if the flag
+ALPHA_MAP_BIT+ flag is set, otherwise Format is set to GL_LUMINANCE.
Notes
glfw::ReadImage supports the Truevision Targa version 1 file format (.TGA). Supported pixel formats
are: 8-bit gray scale, 8-bit paletted (24/32-bit color), 24-bit true color and 32-bit true color + alpha.
Paletted images are translated into true color or true color + alpha pixel formats.
Please note that OpenGL™ 1.0 does not support single component alpha maps, so do not use images
with Format = GL_ALPHA directly as textures under OpenGL™ 1.0.

Width and Height give the dimensions of the image. Format specifies an OpenGL™ pixel format,
which can be GL_LUMINANCE or GL_ALPHA (for gray scale images), GL_RGB or GL_RGBA.
BytesPerPixel specifies the number of bytes per pixel. Data is a pointer to the actual pixel data.
By default the read image is rescaled to the nearest larger 2m × 2n resolution using bilinear
interpolation, if necessary, which is useful if the image is to be used as an OpenGL™ texture. This
behavior can be disabled by setting the +NO_RESCALE_BIT+ flag.
Unless the flag +ORIGIN_UL_BIT+ is set, the first pixel in img-&gt;Data is the lower left corner of
the image. If the flag +ORIGIN_UL_BIT+ is set, however, the first pixel is the upper left corner.
For single component images (i.e. gray scale), Format is set to GL_ALPHA if the flag
+ALPHA_MAP_BIT+ flag is set, otherwise Format is set to GL_LUMINANCE.
Notes
glfw::ReadMemoryImage supports the Truevision Targa version 1 file format (.TGA). Supported pixel
formats are: 8-bit gray scale, 8-bit paletted (24/32-bit color), 24-bit true color and 32-bit true color +
alpha.
Paletted images are translated into true color or true color + alpha pixel formats.
Please note that OpenGL™ 1.0 does not support single component alpha maps, so do not use images
with Format = GL_ALPHA directly as textures under OpenGL™ 1.0.

<!-- Entry for SET-CHAR-CALLBACK -->

<p><br>[Function]<br><a class=none name='set-char-callback'><b>set-char-callback</b> <i>cbfun</i> =&gt; <i>result</i></a>
<blockquote><br><pre>

Parameters
cbfun
       Pointer to a callback function that will be called every time a printable character is generated by
       the keyboard. The function should have the following C language prototype:
       void GLFWCALL functionname( int character, int action );
       Where functionname is the name of the callback function, character is a Unicode (ISO 10646)
       character, and action is either +PRESS+ or +RELEASE+
       If cbfun is NULL, any previously selected callback function will be deselected.
Return values
none
Description
The function selects which function to be called upon a keyboard character event. The callback function
is called every time a key that results in a printable Unicode character is pressed or released. Characters
are affected by modifiers (such as shift or alt).
A window has to be opened for this function to have any effect.
Notes
Character events are recorded continuously, but only reported when glfw::PollEvents, glfw::WaitEvents
or glfw::SwapBuffers is called.
Control characters, such as tab and carriage return, are not reported to the character callback function,
since they are not part of the Unicode character set. Use the key callback function for such events (see
glfw::SetKeyCallback).
The Unicode character set supports character codes above 255, so never cast a Unicode character to an
eight bit data type (e.g. the C language ’char’ type) without first checking that the character code is less
than 256. Also note that Unicode character codes 0 to 255 are equal to ISO 8859-1 (Latin 1).

Parameters
cbfun
      Pointer to a callback function that will be called when a user requests that the window should be
      closed, typically by clicking the window close icon (e.g. the cross in the upper right corner of a
      window under Microsoft Windows). The function should have the following C language
      prototype:
      int GLFWCALL functionname( void );
      Where functionname is the name of the callback function. The return value of the callback
      function indicates wether or not the window close action should continue. If the function returns
      GL_TRUE, the window will be closed. If the function returns GL_FALSE, the window will not
      be closed.
      If cbfun is NULL, any previously selected callback function will be deselected.

      If you declare your callback as returning glfw:boolean, you can use t and nil as return types.

Description
The function selects which function to be called upon a window close event.
A window has to be opened for this function to have any effect.

Notes
Window close events are recorded continuously, but only reported when glfwPollEvents,
glfwWaitEvents or glfwSwapBuffers is called.
The OpenGL™ context is still valid when this function is called.
Note that the window close callback function is not called when glfwCloseWindow is called, but only
when the close request comes from the window manager.
Do not call glfwCloseWindow from a window close callback function. Close the window by returning
GL_TRUE from the function.

Parameters
cbfun
       Pointer to a callback function that will be called when the window client area needs to be
       refreshed. The function should have the following CFFI  prototype:
       (cffi:defcallback callback-name :void ((width :int) (height :int)) .. body ..)

Description
The function restarts one of the threads that are waiting on the condition variable cond. If no threads are
waiting on cond, nothing happens. If several threads are waiting on cond, exactly one is restarted, but it
is not specified which.
Notes
When several threads are waiting for the condition variable, which thread is started depends on
operating system scheduling rules, and may vary from system to system and from time to time.

Parameters
time
        Time, in seconds, to sleep.

Description
The function puts the calling thread to sleep for the requested period of time. Only the calling thread is
put to sleep. Other threads within the same process can still execute.

Notes
There is usually a system dependent minimum time for which it is possible to sleep. This time is
generally in the range 1 ms to 20 ms, depending on thread sheduling time slot intervals etc. Using a
shorter time as a parameter to glfw::Sleep can give one of two results: either the thread will sleep for the
minimum possible sleep time, or the thread will not sleep at all (glfw::Sleep returns immediately). The
latter should only happen when very short sleep times are specified, if at all.

<!-- Entry for SWAP-INTERVAL -->

<p><br>[Function]<br><a class=none name='swap-interval'><b>swap-interval</b> <i>interval</i> =&gt; <i>result</i></a>

Parameters
interval
      Minimum number of monitor vertical retraces between each buffer swap performed by
      glfwSwapBuffers. If interval is zero, buffer swaps will not be synchronized to the vertical
      refresh of the monitor (also known as ’VSync off’).

Description
The function selects the minimum number of monitor vertical retraces that should occur between two
buffer swaps. If the selected swap interval is one, the rate of buffer swaps will never be higher than the
vertical refresh rate of the monitor. If the selected swap interval is zero, the rate of buffer swaps is only
limited by the speed of the software and the hardware.

This function will only have an effect on hardware and drivers that support user selection of the swap
interval.

<!-- Entry for WAIT-COND -->

<p><br>[Function]<br><a class=none name='wait-cond'><b>wait-cond</b> <i>cond mutex timeout</i> =&gt; <i>result</i></a>
<blockquote><br><pre>

  arameters
cond
       A condition variable object handle.
mutex
       A mutex object handle.
timeout
       Maximum time to wait for the condition variable. The parameter can either be a positive time (in
       seconds), or +INFINITY+
Description
The function atomically unlocks the mutex specified by mutex, and waits for the condition variable cond
to be signaled. The thread execution is suspended and does not consume any CPU time until the
condition variable is signaled or the amount of time specified by timeout has passed. If timeout is
+INFINITY+ glfw::WaitCond will wait forever for cond to be signaled. Before returning to the
calling thread, glfw::WaitCond automatically re-acquires the mutex.
Notes
The mutex specified by mutex must be locked by the calling thread before entrance to glfw::WaitCond.
A condition variable must always be associated with a mutex, to avoid the race condition where a thread
prepares to wait on a condition variable and another thread signals the condition just before the first
thread actually waits on it.

<!-- Entry for WAIT-EVENTS -->

<p><br>[Function]<br><a class=none name='wait-events'><b>wait-events</b> <i></i> =&gt; <i>result</i></a>
<blockquote><br><pre>

Description
The function is used for waiting for events, such as user input and window resize events. Upon calling
this function, the calling thread will be put to sleep until any event appears in the event queue. When
events are ready, the events will be processed just as they are processed by glfwPollEvents.
If there are any events in the queue when the function is called, the function will behave exactly like
glfwPollEvents (i.e. process all messages and then return, without blocking the calling thread).

Notes
It is guaranteed that glfwWaitEvents will wake up on any event that can be processed by
glfw::PollEvents. However, glfwWaitEvents may wake up on events that are not processed or reported
by glfw::PollEvents too, and the function may behave differently on different systems. Do no make any
assumptions about when or why glfw::WaitEvents will return.
