DMUS_EVENTHEADER

Precedes and describes an event in a port buffer.

typedef struct _DMUS_EVENTHEADER {
    DWORD           cbEvent;
    DWORD           dwChannelGroup;
    REFERENCE_TIME  rtDelta;
    DWORD           dwFlags;
} DMUS_EVENTHEADER, *LPDMUS_EVENTHEADER;

Members

cbEvent
Number of bytes in the event.
dwChannelGroup
Group to which the event belongs.
rtDelta
Offset from the start time of the buffer.
dwFlags
Set to DMUS_EVENT_STRUCTURED if the event is parsable MIDI data.

Remarks

The Pshpack4.h header file is included before the declaration of this structure to turn off automatic alignment of structures so that the data immediately follows the header. (For more information, see the comments in Pshpack4.h.) Poppack.h is then included to turn alignment back on, and the entire structure (header plus event) is padded to an 8-byte boundary.

Requirements

  Header: Declared in dmusbuff.h.
