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 only compares the first n characters 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.
