swab(3C)                       DG/UX R4.11MU05                      swab(3C)


NAME
       swab - swap bytes

SYNOPSIS
       #include <stdlib.h>

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

DESCRIPTION
       swab copies nbytes bytes pointed to by from to the array pointed to
       by to, exchanging adjacent even and odd bytes.  nbytes should be even
       and non-negative.  If nbytes is odd and positive, swab uses nbytes-1
       instead. If nbytes is negative, swab does nothing.
