NAME
strcasecmp, strncasecmp - compare two strings ignoring case
SYNOPSIS
#include <strings.h>
int strcasecmp(const char *s1, const char *s2);
int strncasecmp(const char *s1, const char *s2, size_t n);
DESCRIPTION
The strcasecmp() function compares the two strings s1 and s2, ignoring
the case of the characters. It returns an integer less than, equal to,
or greater than zero if s1 is found, respectively, to be less than, to
match, or be greater than s2.
The strncasecmp() function is similar, except it compares the only
first n bytes of s1.
RETURN VALUE
The strcasecmp() and strncasecmp() functions return an integer less
than, equal to, or greater than zero if s1 (or the first n bytes
thereof) is found, respectively, to be less than, to match, or be
greater than s2.
CONFORMING TO
4.4BSD, POSIX.1-2001.
