.SH DESCRIPTION
The
.BR libsimple_rawmemcasechr_inv ()
function scans the memory segment
.I s
for the first occurence of any byte
other than
.I c
(it is converted to a
.BR char ).
.PP
The
.BR libsimple_rawmemcasechr_inv ()
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_rawmemcasechr_inv ()
function returns the pointer
.I s
with a minimal offset such that
.IR tolower(*r)!=tolower(c) ,
where
.I r
is the returned pointer.

.SH ERRORS
The
.BR libsimple_rawmemcasechr_inv ()
