.TH LIBSIMPLE_STRNCASECHRNUL 3 libsimple
.SH NAME
libsimple_strncasechrnul \- find a character in a string
.SH SYNOPSIS
.nf
#include <libsimple.h>
char *libsimple_strncasechrnul(const char *\fIs\fP, int \fIc\fP, size_t \fIn\fP);
#ifndef strncasechrnul
# define strncasechrnul libsimple_strncasechrnul
#endif

Link with
.IR \-lsimple .
.SH DESCRIPTION
The
.BR libsimple_strncasechrnul ()
function scans the string
.IR s ,
truncated to
.I n
bytes unless it is shorter,
for the first occurence of the character
.I c
(it is converted to a
.BR char ).
If no such character exist in the string,
the string's end is returned.
.PP
The comparison is case-insensitive.
.SH RETURN VALUE
The
.BR libsimple_strncasechrnul ()
function returns the pointer
.I s
with a minimal offset such that
.IR tolower(*r)==tolower(c)||!*r ,
where
.I r
is the returned pointer. However if no such
offset less than
.I n
exists,
.B NULL
is returned.
.SH ERRORS
The
.BR libsimple_strncasechrnul ()
function cannot fail.
