NAME

       swab - Swaps bytes

LIBRARY

       Standard C Library (libc.so, libc.a)

SYNOPSIS

       #include <unistd.h>

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

       The following definition of the swab() function does not conform to current standards and is supported only for System V compatibility:

       void swab(
	       const char *from,
	       char *to,
	       int nbytes);

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       swab():	XPG4, XPG4-UNIX

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS

       Points  to  the	location  of the string to copy.  Points to the location to which the resulting string is copied.  Specifies the number of
       bytes to be copied.  The nbytes parameter should have an even value.  When the nbytes parameter is odd, the swab() function  uses  nbytes-1
       instead.  For the System V version of the swab() function, nbytes must also be non-negative.  If nbytes is negative, nothing is done.

DESCRIPTION

       The  swab()  function copies the number of bytes specified by the nbytes parameter from the location pointed to by the src parameter to the
       array pointed to by the dest parameter, exchanging adjacent bytes. If copying takes place between objects that  overlap,  the  behavior	is
       undefined.
