Standard C Library Functionsswab(3C)

NAME

 swab - swap bytes

SYNOPSIS

Default

 
  
#include <stdlib.h>
void swab(const void *src, char *dest, ssize_t nbytes);

XPG4, SUS, SUSv2

 
  
#include <unistd.h>
void swab(const void *src, void *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
