Article
02/22/2024

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.
