Initializes a condition variable.

Syntax


VOID WINAPI InitializeConditionVariable(
  _Out_  PCONDITION_VARIABLE ConditionVariable
);

Parameters

ConditionVariable [out]

A pointer to the condition variable.

Return value

This function does not return a value.

Remarks

Threads can atomically release a lock and enter the sleeping state using the SleepConditionVariableCS or SleepConditionVariableSRW function. The threads are woken using the WakeConditionVariable or WakeAllConditionVariable function.

Condition variables are user-mode objects that cannot be shared across processes.

A condition variable cannot be moved or copied. The process must not modify the object, and must instead treat it as logically opaque. Only use the condition variable functions to manage condition variables.
