.SH NAME
libsimple_memcasecmp \- compare two memory segments
.SH SYNOPSIS
.nf
#include <libsimple.h>

static inline int libsimple_memcasecmp(const void *\fIa\fP, const void *\fIb\fP, size_t \fIn\fP);

#ifndef memcasecmp
# define memcasecmp libsimple_memcasecmp
#endif

.PP
Link with
.IR \-lsimple .
.SH DESCRIPTION
The
.BR libsimple_memcasecmp ()
function compares the first
.I n
bytes of

The comparison is case-insensitive and made as
if the strings were converted to lowercase and as
.BR "unsigned char *" s.
.SH RETURN VALUE
The
.BR libsimple_memcasecmp ()
function returns a negative value if
.I a
is less than
.IR b ,
a positive value if
.I a
is greater than
.IR b ,
and 0 otherwise.
.SH ERRORS
