Opens a keyed mutex object that includes private data.
unnamedParam1 [in, out]pData
A pointer to a D3DKMT_OPENKEYEDMUTEX2 structure that describes a keyed mutex object that includes private data.
Returns one of the following values:
| Return code | Description |
|---|---|
| STATUS_SUCCESS | The keyed mutex object was successfully opened. |
| 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 | D3DKMTOpenKeyedMutex2 could not complete because of insufficient memory. |
This function might also return other NTSTATUS values.
D3DKMTOpenKeyedMutex2 behaves like the D3DKMTOpenKeyedMutex function but lets the caller specify private data to associate with the keyed mutex.
