.SH DESCRIPTION
The
.BR libsimple_memelemmove ()
and
.BR libsimple_memelemcpy ()
functions copy
.I n
elements,
each with the width
.IR width ,
in
.I src
to
.IR dest .
However the copy stopes after the element
.I elem
(with size
.IR width )
has been copied.
.PP
The arrays may overlap in the
.BR libsimple_memelemmove ()
function but not in the
.BR libsimple_memelemcpy ()
function.

.SH RETURN VALUE
The
.BR libsimple_memelemmove ()
and
.BR libsimple_memelemcpy ()
functions return a pointer directly behind
the position of the element
.I elem
in
.I dest
after it was copied. If the element
.I elem
was not copied
.I NULL
is returned.

.SH ERRORS
The
.BR libsimple_memelemmove ()
and
.BR libsimple_memelemcpy ()
functions cannot fail.
