D3DDDI_UNLOCKFLAGS structure

The D3DDDI_UNLOCKFLAGS structure identifies how to unlock a resource.

Syntax


typedef struct _D3DDDI_UNLOCKFLAGS {
  union {
    struct {
      UINT NotifyOnly  :1;
      UINT Reserved  :31;
    };
    UINT   Value;
  };
} D3DDDI_UNLOCKFLAGS;

Members

NotifyOnly

A UINT value that specifies whether the unlock call is for notification only.

Setting this member is equivalent to setting the first bit of the 32-bit Value member (0x00000001).

Reserved

This member is reserved and should be set to zero. Setting this member to zero is equivalent to setting the remaining 31 bits (0xFFFFFFFE) of the 32-bit Value member to zeros.

Value

A member in the union that is contained in D3DDDI_UNLOCKFLAGS that can hold one 32-bit value that identifies how to unlock a resource.

Requirements

Version

Available in Windows Vista and later versions of the Windows operating systems.
