.TH LIBSIMPLE_MEMRCASECHR_INV 3 2018-11-24 libsimple
.SH NAME
libsimple_memrcasechr_inv \- find byte in memory
.SH SYNOPSIS
.nf
#include <libsimple.h>
void *libsimple_memrcasechr_inv(const void *\fIs\fP, int \fIc\fP, size_t \fIn\fP);
#ifndef memrcasechr_inv
# define memrcasechr_inv libsimple_memrcasechr_inv
#endif
.fi
.PP
Link with
.IR \-lsimple .
.SH DESCRIPTION
The
.BR libsimple_memrcasechr_inv ()
function scans the memory segment
.IR s ,
with the size
.IR n ,
for the last occurence of any byte
other than
.I c
(it is converted to a
.BR char ).
.PP
The comparison is case-insensitive.
.SH RETURN VALUE
The
.BR libsimple_memrcasechr_inv ()
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_inv ()
function cannot fail.
.SH ATTRIBUTES
For an explanation of the terms used in this section, see
