+.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.
+.SH ATTRIBUTES
+For an explanation of the terms used in this section, see
