Define Documentation

#define __VOLATILE

Macro alias to `volatile' semantics. Here it is not truly volatile since it is in a single-threaded environment.

Definition at line 287 of file fast_mutex.h.

#define _FAST_MUTEX_ASSERT	(		_Expr,
			_Msg
	)

Value:

if (!(_Expr)) { \
            fprintf(stderr, "fast_mutex::%s\n", _Msg); \
            abort(); \
        }

Macro for fast_mutex assertions. Real version (for debug mode).

Definition at line 103 of file fast_mutex.h.

#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.
