// #include <stdio.h> // for size_t/* sndconfig.h -- system-specific definitions *//*   NOTES: each implementation must have its own .h and .c files,  e.g. sndwin32.h and sndwin32.c. These files implement the following:1) Either LINUX, WIN32, or MACINTOSH should be defined.(WX can also be defined to override standard file IO with functionsfrom WX, a graphical user interface library.)2) The following function declaration:    void snd_fail(char *msg);or    #define snd_fail some_function(note that snd_fail must be a function pointer)3) typedef FASTFLOAT to be either a double or a float, whichevercomputes faster (PowerPCs are faster at double math than float math)4) typedef MEMFLOAT to be how you would store a sample in memory(this should normally be float)5) min() must be defined (either a macro or a function)6) max() must be defined (either a macro or a function)7) the following file IO functions must be defined:    int snd_file_open(char *fname, int mode);    int snd_file_creat(char *fname);    int snd_file_lseek(int file, int offset, int param);    long snd_file_read(int fp, char *data, long len);    long snd_file_write(int fp, char *data, long len);    int snd_file_close(int fp);    long snd_file_len(int fp);(some implementations cast a pointer to an int in snd_open,so it is assumed that int can at least hold a pointer)8) The following function to report failure and exit:    void snd_fail(char *msg);9) The following memory allocation routines:    void *snd_alloc(size_t s);    void snd_free(void *a);10) snd_string_max -- string length for filenames, etc.*/#define snd_string_max 258void snd_fail(char *msg);void snd_warn(char *msg);void *snd_alloc(size_t s);void snd_free(void *a);#if defined(__linux__)  #include "sndlinux.h"#elif defined(IRIX)  #include "sndirix.h"#elif defined(__FreeBSD__)  #include "sndfreebsd.h"#elif defined(_WIN32)  #ifndef WIN32    #define WIN32  #endif  #include "sndwin32.h"#elif defined(macintosh) || defined(__WXMAC__) || defined(__APPLE__)  #ifndef MAC    #define MAC  #endif  #include "sndmac.h"#endif
