D3DKMT_ACQUIREKEYEDMUTEX structure (d3dkmthk.h)

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

Syntax

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

Members

[in] hKeyedMutex

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

[in] Key

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

void D3DKMT_PTR( PLARGE_INTEGER unnamedParam1, pTimeout unnamedParam2)

[out] FenceValue

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

Requirements

   
Minimum supported client D3DKMT_ACQUIREKEYEDMUTEX is supported beginning with the Windows 7 operating system.
