PROLOG        top

       This manual page is part of the POSIX Programmer's Manual.  The       Linux implementation of this interface may differ (consult the       corresponding Linux manual page for details of Linux behavior), or       the interface may not be implemented on Linux.

NAME        top

       swab — swap bytes

SYNOPSIS        top

       #include <unistd.h>       void swab(const void *restrictsrc, void *restrictdest,           ssize_tnbytes);

DESCRIPTION        top

       Theswab() function shall copynbytes bytes, which are pointed to       bysrc, to the object pointed to bydest, exchanging adjacent       bytes. Thenbytes argument should be even. Ifnbytes is odd,swab() copies and exchangesnbytes-1 bytes and the disposition of       the last byte is unspecified. If copying takes place between       objects that overlap, the behavior is undefined.  Ifnbytes is       negative,swab() does nothing.

RETURN VALUE        top
