1. Parameter icond is not null.

Member Function Documentation

void Cond::broadcast ( )

inline

Resumes all threads that are waiting for the condition.

Calling the method without no threads waiting for signals have no effect.

void Cond::signal ( )

void Cond::wait ( Mutex &  mutex )

inline

The calling thread will wait until the condition variable is signaled by another thread.

This method atomically performs this steps:

• unlocks the passed mutex.
• wait for a signal from another thread (see methods signal and broadcast).
• locks again the mutex.
