PFND3DKMT_OPENKEYEDMUTEX2 callback function (d3dkmthk.h)

Opens a keyed mutex object that includes private data.

Syntax

PFND3DKMT_OPENKEYEDMUTEX2 Pfnd3dkmtOpenkeyedmutex2;

NTSTATUS Pfnd3dkmtOpenkeyedmutex2(
  [in, out] D3DKMT_OPENKEYEDMUTEX2 *unnamedParam1
)
{...}

[in, out] unnamedParam1

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.
