.SH DESCRIPTION
The
.BR libsimple_memtolower ()
and
.BR libsimple_memptolower ()
functions copies the first
.I n
characters from the array
.I src
into the
.I array.
All upper case ASCII characters will be converted
to lower case. The arrays may overlap, and there
is an optimisation for the case where
.IR dest==src .

.SH RETURN VALUE
The
.BR libsimple_memtolower ()
function returns the pointer
.IR dest .
.PP
The
.BR libsimple_memptolower ()
function returns
.IR &dest[n] .

.SH ERRORS
The
.BR libsimple_memtolower ()
and
.BR libsimple_memptolower ()
functions cannot fail.
