Sharing constants

Constants for file-sharing modes.

Syntax

#include <share.h>

Remarks

The shflag argument determines the sharing mode, which consists of one or more manifest constants. These constants can be combined with the oflag arguments (see File constants).

The following table lists the constants and their meanings:

Constant	Meaning
_SH_DENYRW	Denies read and write access to file
_SH_DENYWR	Denies write access to file
_SH_DENYRD	Denies read access to file
_SH_DENYNO	Permits read and write access
_SH_SECURE	Sets secure mode (shared read, exclusive write access).
