D3DKMT_CREATEKEYEDMUTEX2_FLAGS structure (d3dkmthk.h)
Indicates how a handle to a keyed mutex is specified.
Syntax
typedef struct _D3DKMT_CREATEKEYEDMUTEX2_FLAGS {
union {
struct {
UINT NtSecuritySharing : 1;
UINT Reserved : 31;
};
[in] UINT Value;
};
} D3DKMT_CREATEKEYEDMUTEX2_FLAGS;
Members
NtSecuritySharing
A UINT value that specifies whether the keyed mutex is shared or has a global D3DKMT_HANDLE kernel-mode handle to the resource.
If NtSecuritySharing is set to 1 (TRUE), the keyed mutex is shared using the D3DKMTShareObjects function but does not have a global D3DKMT_HANDLE handle to the resource. In this case, the process handle to the resource is provided by the D3DKMT_CREATEKEYEDMUTEX2.hKeyedMutex member in a call to the D3DKMTCreateKeyedMutex2 function.
If NtSecuritySharing is set to zero (FALSE), the keyed mutex has a global D3DKMT_HANDLE handle to the resource provided by the D3DKMT_CREATEKEYEDMUTEX2.hSharedHandle member in a call to D3DKMTCreateKeyedMutex2.
Reserved
This member is reserved and should be set to zero. Setting this member is equivalent to setting the remaining 31 bits (0xFFFFFFFE) of a 32-bit value to zeros.
[in] Value
A member in the union that D3DKMT_CREATEKEYEDMUTEX2_FLAGS contains that can hold a 32-bit value that identifies the keyed mutex sharing type.
