This directory contains the small example programs from Multimedia on
Linux.

dsp_info	- show /dev/dsp capabilities
eject.c		- eject CD-ROM
joystick.c	- reading joystick device
mixer.c		- simple sound mixer program
mixer_info.c	- display sound mixer settings
multisess.c	- display CD multi-session info

readaudio.c	- example of reading digital audio
seq_info.c	- display sequencer device info
subchnl.c	- display subchannel info
syscalls.c	- illustrates open/ioctl/close system calls

All program can be built by typing "make". They have been compiled and
tested under Linux 1.1, 1.2, 1.3, and 2.0 but may need some minor
changes depending on your Linux distribution.

The joystick program requires the kernel joystick driver which must be
obtained separately.

Some of the programs assume that the CD-ROM device to use is
/dev/cdrom. If necessary, either create a symbolic link to your CD-ROM
device in /dev or modify the source code.

Not all CD-ROM drives support the CDROMREADAUDIO function used by
readaudio.
