SWAB(3C)SWAB(3C)NAMEswab - 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
unspecified. If copying takes place between objects that overlap, the
behavior is undefined. If nbytes is negative, swab() does nothing.
ERRORS
No errors are defined.
