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.
