NAME

       swab - swap bytes

SYNOPSIS

       #include <stdlib.h>

       void swab(const char *src, char *dest, ssize_t nbytes);

   XPG4, SUS, SUSv2, SUSv3
       #include <unistd.h>

       void swab(const void *restrict src, void *restrict dest, ssize_t nbytes);

DESCRIPTION

       The  swab()  function  copies  nbytes bytes, which are pointed to by src, to the object pointed to by dest, exchanging adjacent bytes.  The
       nbytes argument should be even. If nbytes is odd swab() copies and exchanges nbytes-1 bytes and the disposition of the last byte is unspec-
       ified. If copying takes place between objects that overlap, the behavior is undefined. If nbytes is negative, swab() does nothing.

ERRORS

       No errors are defined.
