Notifies all of the threads waiting on a specified condition variable.


#include <prcvar.h>

PRStatus PR_NotifyAllCondVar(PRCondVar *cvar);


The function returns one of the following values:

  • If successful, PR_SUCCESS.
  • If unsuccessful (for example, if the caller has not locked the lock associated with the condition variable), PR_FAILURE.


The calling thread must hold the lock that protects the condition, as well as the invariants that are tightly bound to the condition.

A call to PR_NotifyAllCondVar causes all of the threads waiting on the specified condition variable to be promoted to a ready state. If no threads are waiting, the operation is no-op.
