MMIO_WINMSG

This structure contains information used on an MMIOM_WINMSG message.

Note

The fields of this structure correspond to the parameters of the WinSendMsg and WinPostMsg functions.

The digital video device sends WM_DESTROYCLIPBOARD messages to the I/O procedure. Since it ignores the return code from the message, movie file I/O procedures are not required to support MMIOM_WINMSG.

   typedef struct _MMIO_WINMSG {

     PVOID      pParam2;     /* Second PM message parameter. */
   } MMIO_WINMSG;
