Includes

The include files cascade in this order:

• "sox_i.h"
  • "soxomp.h"
    • "soxconfig.h"
    • <omp.h>
  • "sox_ng.h"
    • <limits.h>
    • <stdarg.h>
    • <stddef.h>
  • "util.h"
    • <stdio.h>
    • <stdlib.h>
    • "soxconfig.h"
    • <sys/types.h>
    • <sys/stat.h>
    • "xmalloc.h"
      • <stddef.h>
      • <string.h>
      • <strings.h>
    • <inttypes.h> or <stdint.h>
    • <math.h>
  • <assert.h>
  • <errno.h>
  • <byteswap.h>
  • "effects.h"
  • <ltdl.h>

sox_ng.h is included by users of libsox_ng.

sox_i.h is included by sox-internal source files.

sox_ng.c is the only source file not to include sox_i.h because it is a user of libsox_ng, but it does include util.h for the sox_* type definitions and portability hacks.

That leaves individual source files to include, if needed:

• <ctype.h>
• <fcntl.h>
• <io.h>
• <stropts.h>
• <unistd.h>
