WakeConditionVariable function

Wake a single thread waiting on the specified condition variable.

Syntax

void WakeConditionVariable(
  PCONDITION_VARIABLE ConditionVariable
);

Parameters

ConditionVariable

A pointer to the condition variable.

Return value

This function does not return a value.

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).
