Notifies all of the threads waiting on a specified condition variable.
Syntax
#include <prcvar.h> PRStatus PR_NotifyAllCondVar(PRCondVar *cvar);
Returns
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.
Description
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.
