+/*
+ * pmlinuxnull.c -- system specific definitions
+ *
+ * written by:
+ * Roger Dannenberg
+ *
+ * If there is no ALSA, you can define PMNULL and build PortMidi. It will
+ * not report any devices, so you will not be able to open any, but if
+ * you wanted to disable MIDI from some application, this could be used.
+ * Mainly, this code shows the possibility of supporting multiple
+ * interfaces, e.g., ALSA and Sndio on BSD, or ALSA and Jack on Linux.
+ * But as of Dec, 2021, the only supported MIDI API for Linux is ALSA.
