.SH DESCRIPTION
The
.BR libsimple_rawmemrcasechr ()
function scans the memory segment
.IR s ,
with the size
.IR n ,
for the last occurence of the byte
.I c
(it is converted to a
.BR char ).

.BR libsimple_rawmemrcasechr ()
function assumes there is at least one
occurence, its behaviour is undefined
if this is not the case.
.PP
The comparison is case-insensitive.
.SH RETURN VALUE
The
.BR libsimple_rawmemrcasechr ()
function returns the pointer
.I s
with a maximal offset such that
.IR tolower(*r)==tolower(c) ,
where
.I r
is the returned pointer.
