IBroadcastEventEx::FireEx Method

This topic applies to Update Rollup 2 for Microsoft Windows XP Media Center Edition 2005.
The FireEx method fires a broadcast event.

Syntax

HRESULT FireEx(
  [in]  GUID EventID,
  [in]  ULONG Param1,
  [in]  ULONG Param2,
  [in]  ULONG Param3,
  [in]  ULONG Param4
);

Parameters

  • EventID [in]
    GUID that specifies the event.

  • Param1 [in]
    Specifies the first implementation-dependent parameter.

  • Param2 [in]
    Specifies the second implementation-dependent parameter.

  • Param3 [in]
    Specifies the third implementation-dependent parameter.

  • Param4 [in]
    Specifies the fourth implementation-dependent parameter.

Return Value

If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

This method is similar to IBroadcastEvent::Fire, but it includes four additional parameters for passing implementation-dependent information between the object that fires the event and the objects that wait on the event. The designer who implements the objects must determine what meaning, if any, to assign to these parameters.

Requirements

Header Declared in Dshow.h.
DLL Requires Quartz.dll.
