Define Documentation

#define __VOLATILE   volatile

Macro alias to `volatile' semantics.

Here it is truly volatile since it is in a multi-threaded (POSIX threads) environment.

#define _FAST_MUTEX_ASSERT	(	_Expr,
		_Msg		)	((void)0)

Macro for fast_mutex assertions.

Fake version (for release mode).

#define _FAST_MUTEX_CHECK_INITIALIZATION   1

Macro to control whether to check for initialization status for each lock/unlock operation.

Defining it to a non-zero value will enable the check, so that the construction/destruction of a static object using a static fast_mutex not yet constructed or already destroyed will work (with lock/unlock operations ignored). Defining it to zero will disable to check.
