.SH DESCRIPTION
The
.BR libsimple_memchr_inv ()
function scans the memory segment
.IR s ,
with the size
.IR n ,
for the first occurence of any byte
other than
.I c
(it is converted to a
.BR char ).
.PP
The comparison is case-sensitive.

.SH RETURN VALUE
The
.BR libsimple_memchr_inv ()
function returns the pointer
.I s
with a minimal offset such that
.IR *r!=c ,
where
.I r
is the returned pointer.
If no such offset exists,
.B NULL
is returned.

.SH ERRORS
The
.BR libsimple_memchr_inv ()
function cannot fail.
