Detailed Description

class Mutex This class encapsulates a pthread Mutex

Member Function Documentation

bool Mutex::busy (  ) 

Checks whether the mutex is locked or not.

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.

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