// Last Modified: Thu May 18 23:36:07 PDT 2000 (added ifdef LINUX lines)

// Filename: ...sig/maint/code/control/MidiInPort/MidiInPort_linux.h
// Web Address: http://sig.sapp.org/include/sig/MidiInPort_linux.h
// Syntax: C++
//
// Description: An interface for MIDI input capabilities of an
// operating-system specific MIDI input method.
// Provides control of all low-level MIDI input
// functionality such that it will work on all
// computers in the same manner.
