BRELS_TRACK_HEADER structure

BRELS_TRACK_HEADER

typedef struct
{
	DWORD dwMagic;
	DWORD dwLength;
} BRELS_TRACK_HEADER, *LPBRELS_TRACK_HEADER;

This is header of the tracks as found in a MIDI file. The track header precedes every track in the file.

Members

dwMagic: "magic" number which identifies MIDI tracks. It is always 0x4D54726B (MTrk)
dwLength: size of the encoded track data.

Remarks

Due to the difference between the storage method of the file and its memory representation, the byte order of values in each member of the structure is reversed. Use btldw to correct them:

Example

void CorrectTrackHeader(LPBRELS_TRACK_HEADER lpbth)
{
	lpbth->dwMagic = btldw(lpbth->dwMagic);
	lpbth->dwLength = btldw(lpbth->dwLength);
};
