.SH NAME
libsimple_rawmemrcasechr \- find byte in memory
.SH SYNOPSIS
.nf
#include <libsimple.h>
void *libsimple_rawmemrcasechr(const void *s, int c, size_t n);
#ifndef rawmemrcasechr
# define rawmemrcasechr libsimple_rawmemrcasechr
#endif
.fi
.PP
Link with
.IR \-lsimple .
.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 ).
.PP
The
.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.
.SH ERRORS
The
.BR libsimple_rawmemrcasechr ()
function cannot fail.
