HELPLIB.HLB  —  CRTL  swab
    Swaps bytes.

    Format

      #include  <unistd.h>

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

1  –  Arguments

 src

    A pointer to the location of the string to copy.

 dest

    A pointer to where you want the results copied.

 nbytes

    The number of bytes to copy. Make this argument an even value.
    When it is an odd value, the swab function uses nbytes -1
    instead.

2  –  Description

    The swab function copies the number of bytes specified by nbytes
    from the location pointed to by src to the array pointed to by
    dest. The function then exchanges adjacent bytes. If a copy takes
    place between objects that overlap, the result is undefined.
