D3DKMTCreateKeyedMutex2 function (d3dkmthk.h)
Creates a keyed mutex object that includes private data.
Syntax
NTSTATUS D3DKMTCreateKeyedMutex2(
D3DKMT_CREATEKEYEDMUTEX2 *unnamedParam1
);
Parameters
unnamedParam1
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 code | Description |
|---|---|
| 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.
