      int strncasecmp(const char * s1 , const char * s2 , size_t  n ); 

• DESCRIPTION
  
  The
  strcasecmp ()
  function compares the two strings s1 and

  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.
