NAME

       midi_msg_callback,  midi_meta_callback,  midi_sysex_callback - Hook functions allowing you
       to intercept MIDI player events. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       extern void (*midi_msg_callback)(int msg, int byte1, int byte2);

       extern void (*midi_meta_callback)(int type, const unsigned char *data, int length);

       extern void (*midi_sysex_callback)(const unsigned char *data, int length);

DESCRIPTION

       Hook functions allowing you to intercept MIDI player events. If set to anything other than
       NULL,  these  routines  will  be  called  for  each  MIDI  message, meta-event, and system
       exclusive data block respectively. They will execute in an interrupt handler  context,  so
       all  the  code  and  data  they use should be locked, and they must not call any operating
       system functions. In general you just use these routines to set some flags and respond  to
       them later in your mainline code.
