D3DDDI_SYNCHRONIZATIONOBJECTINFO structure (d3dukmdt.h)

The D3DDDI_SYNCHRONIZATIONOBJECTINFO structure contains information about a synchronization object.

Syntax

typedef struct _D3DDDI_SYNCHRONIZATIONOBJECTINFO {
  [in] D3DDDI_SYNCHRONIZATIONOBJECT_TYPE Type;
  union {
    struct {
      BOOL InitialState;
    } SynchronizationMutex;
    struct {
      UINT MaxCount;
      UINT InitialCount;
    } Semaphore;
    struct {
      UINT Reserved[16];
    } Reserved;
  };
} D3DDDI_SYNCHRONIZATIONOBJECTINFO;

Members

[in] Type

A D3DDDI_SYNCHRONIZATIONOBJECT_TYPE-typed value that indicates the type of synchronization object.

SynchronizationMutex

A structure that contains information about a synchronization mutex. If the Type member is equal to D3DDDI_SYNCHRONIZATION_MUTEX, the union in D3DDDI_SYNCHRONIZATIONOBJECTINFO holds a SynchronizationMutex structure, which contains the following member:

SynchronizationMutex.InitialState

A Boolean value that indicates whether the synchronization mutex is initially owned by an object. A value of TRUE indicates that the mutex is owned; FALSE indicates that the mutex is not owned.

Semaphore

A structure that contains information about a semaphore. If the Type member is equal to D3DDDI_SEMAPHORE, the union in D3DDDI_SYNCHRONIZATIONOBJECTINFO holds a Semaphore structure, which contains the following members:

Semaphore.MaxCount

The maximum number of events that an object can be waiting for.

Semaphore.InitialCount

The initial number of events that an object is waiting for.

Reserved

A structure that is reserved for future use. This structure contains the following member:

Reserved.Reserved[16]

An array of 32-bit values that are reserved for future use.
