Syntax

char *_getdcwd_nolock(
   int drive,
   char *buffer,
   int maxlen
);
wchar_t *_wgetdcwd_nolock(
   int drive,
   wchar_t *buffer,
   int maxlen
);

Parameters

drive
Disk drive.

buffer
Storage location for the path.

maxlen
Maximum length of path in characters: char for _getdcwd_nolock and wchar_t for _wgetdcwd_nolock.

Return value

See _getdcwd, _wgetdcwd.

Remarks

_getdcwd_nolock and _wgetdcwd_nolock are identical to _getdcwd and _wgetdcwd, respectively, except that they aren't protected from interference by other threads. They might be faster because they don't incur the overhead of locking out other threads. Use these functions only in thread-safe contexts such as single-threaded applications or where the calling scope already handles thread isolation.
