InitializeSRWLock function

Initialize a slim reader/writer (SRW) lock.

Syntax


VOID WINAPI InitializeSRWLock(
  _Out_  PSRWLOCK SRWLock
);

Parameters

SRWLock [out]

A pointer to the SRW lock.

Return value

This function does not return a value.

Remarks

An SRW lock must be initialized before it is used. The InitializeSRWLock function is used to initialize a SRW lock dynamically. To initialize the structure statically, assign the constant SRWLOCK_INIT to the structure variable.

An SRW lock cannot be moved or copied. The process must not modify the object, and must instead treat it as logically opaque. Only use the SRW functions to manage SRW locks.

SRW locks do not need to be explicitly destroyed.
