Standard C Library Functions                             swab(3C)



NAME
     swab - swap bytes

SYNOPSIS
     #include 

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


  XPG4, SUS, SUSv2, SUSv3
     #include 

     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.
