.TH LIBSIMPLE_MEMRCASECHR 3 libsimple
.SH NAME
libsimple_memrcasechr \- find byte in memory
.SH SYNOPSIS
.nf
#include <libsimple.h>
void *libsimple_memrcasechr(const void *\fIs\fP, int \fIc\fP, size_t \fIn\fP);
#ifndef memrcasechr
# define memrcasechr libsimple_memrcasechr
#endif
.fi
.PP
Link with
.IR \-lsimple .
.SH DESCRIPTION
The
.BR libsimple_memrcasechr ()
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 comparison is case-insensitive.
.SH RETURN VALUE
The
.BR libsimple_memrcasechr ()
function returns the pointer
.I s
with a maximal offset such that
.IR tolower(*r)==tolower(c) ,
where
.I r
is the returned pointer.
If no such offset exists,
.B NULL
is returned.
.SH ERRORS
The
.BR libsimple_memrcasechr ()
function cannot fail.
