D3DKMT_ACQUIREKEYEDMUTEX structure (d3dkmthk.h)

The D3DKMT_ACQUIREKEYEDMUTEX structure describes a keyed mutex that the D3DKMTAcquireKeyedMutex function acquires.

Syntax

typedef struct _D3DKMT_ACQUIREKEYEDMUTEX {
  D3DKMT_HANDLE         hKeyedMutex;
  D3DKMT_ALIGN64 UINT64 Key;
  void                  D3DKMT_PTR(
    PLARGE_INTEGER unnamedParam1,
    pTimeout       unnamedParam2
  );
  D3DKMT_ALIGN64 UINT64 FenceValue;
} D3DKMT_ACQUIREKEYEDMUTEX;

Members

hKeyedMutex

[in] A D3DKMT_HANDLE data type that represents a kernel-mode handle to the keyed mutex object to acquire.

Key

[in] A 64-bit value that specifies the key value to acquire the mutex for.

void D3DKMT_PTR( PLARGE_INTEGER unnamedParam1, pTimeout unnamedParam2)

FenceValue

[out] A 64-bit value that specifies the current fence value of the GPU synchronization object.
