swab



PURPOSE

Copies bytes.

LIBRARY

Standard C Library (libc.a)

SYNTAX

void swab (from, to, nbytes)
short *from, *to;
int nbytes;

DESCRIPTION

The swab subroutine copies nbytes bytes from the location pointed to by the
from parameter to the array pointed to by the to parameter, exchanging adjacent
even and odd bytes.

The nbytes parameter should be even and nonnegative.  If the nbytes parameter
is odd and positive, the swab uses nbytes-1 instead.  If the nbytes parameter
is negative, then swab does nothing.
