/* SoundIt library 0.03   Copyright 1994 Brad Pitzel  pitzel@cs.sfu.ca   Feel free to use/distribute/modify as long as proper credits   are included.*/ /* Designed for digital sound effects in games.   Will mix channels of mono 8-bit raw samples, & play back in "real-time".   Each channel can only play one sample at a time, but all   channels can play a different sample simultaneously.                       If you have sox, use the ' -t .ub ' option to make samples   that this library will play properly.   I wrote this in C, instead of C++, so hopefully a few more people will   take a look and make it better :-)*/#ifndef SOUNDIT_VERS#define SOUNDIT_VERS "0.03"#include <stdlib.h>#include <stdio.h>/* 00002 = 2 fragments   *//* 00007 = means each fragment is 2^7 or 128 bytes *//* See voxware docs (in /usr/src/linux/drivers/sound) for more info */#define FRAG_SPEC 0x00020007/*==========================================================================*/struct Sample    {    unsigned char *data;	/* unsigned 8-bit raw samples */    int len;			/* length of sample in bytes  */    };typedef struct Sample Sample;/* given the name of a .raw sound file, load it into the Sample struct */ /* pointed to by 'sample'                                              */intSnd_loadRawSample( const char *file, Sample *sample );/*==========================================================================*//* init sound device, etc..                                                 *//* num_snd  = the number of samples in the sample array *sa                 *//* sa       = the sample array						    *//* freq     = the rate (Hz) to play back the samples                        *//* channels = # of channels to mix                                          *//* sound_device = a char string for the sound device, eg, "/dev/dsp"        *//* returns: 0=success, -1=failure.*/int Snd_init( int num_snd, const Sample *sa, int freq,           int channels, const char *sound_device );/* shutdown sample player, free mem, etc/etc..*/int Snd_restore();/* play a sound effect in the given channel 1..n*//* volume = integers from 0 (off) to 100 (full volume)*/int Snd_effect( int nr, int channel );/* stop a channel (1..n) from playing*//*void Snd_reset(enum snd_channel channel);*//* stop all channels from playing*//*void Snd_reset();*/	#endif
