Member Function Documentation

bool wait (  Condition  cond  )

Wait for cond. If the supplied condition cond is false the current process is blocked until the condition is true and signal() was called. If a blocked process is interrupted, it is reactivated and the function returns false. (An interrupted process has influence on the queue-statistic but not on user and waiting time statistics.)
