Member Function Documentation

bool Mutex::busy

(

)

Checks whether the mutex is locked or not.

Returns:

true if the mutex is locked, false otherwise.

References _mtx.

int Mutex::release

(

)

Releases the Mutex.

Note: This class emulates a recursive mutex. One needs as many calls to release as calls where made to acquire.

Returns:

the number of times this function still needs to be called to really release the Mutex

References _count, _mtx, _owner, and debug.
