D3DKMTCreateKeyedMutex2 function

Creates a keyed mutex object that includes private data.

Syntax


EXTERN_C _Check_return_ NTSTATUS APIENTRY D3DKMTCreateKeyedMutex2(
  _Inout_  D3DKMT_CREATEKEYEDMUTEX2 *pData
);

Parameters

pData [in, out]

A pointer to a D3DKMT_CREATEKEYEDMUTEX2 structure that describes a keyed mutex object to create.

Return value

Returns one of the following values:

Return codeDescription
STATUS_SUCCESS

The keyed mutex object was successfully created.

STATUS_DEVICE_REMOVED

The graphics adapter was stopped or the display device was reset.

STATUS_INVALID_PARAMETER

Parameters were validated and determined to be incorrect.

STATUS_NO_MEMORY

D3DKMTCreateKeyedMutex2 could not complete because of insufficient memory.

 

This function might also return other NTSTATUS values.

Remarks

D3DKMTCreateKeyedMutex2 behaves like the D3DKMTCreateKeyedMutex function but lets the caller specify private data to associate with the keyed mutex.

Keyed mutexes created with D3DKMTCreateKeyedMutex2 are still compatible with D3DKMTOpenKeyedMutex, D3DKMTAcquireKeyedMutex, and D3DKMTReleaseKeyedMutex functions.
