WakeAllConditionVariable function (synchapi.h)

Wake all threads waiting on the specified condition variable.

Syntax

void WakeAllConditionVariable(
  [in, out] PCONDITION_VARIABLE ConditionVariable
);

Parameters

[in, out] ConditionVariable

A pointer to the condition variable.

Return value

None

Remarks

The WakeAllConditionVariable wakes all waiting threads while the WakeConditionVariable wakes only a single thread. Waking one thread is similar to setting an auto-reset event, while waking all threads is similar to pulsing a manual reset event but more reliable (see PulseEvent for details).
