NAME
       strcasecmp, strncasecmp - case-insensitive string comparisons

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  shall compare, while ignoring differences in case, the string
       pointed to by s1 to the string pointed to by s2. The strncasecmp() function shall compare,
       while ignoring differences in case, not more than n bytes from the string pointed to by s1
       to the string pointed to by s2.

       In the POSIX locale, strcasecmp() and strncasecmp() shall behave as  if	the  strings  had
       been converted to lowercase and then a byte comparison performed. The results are unspeci-
       fied in other locales.

RETURN VALUE
       Upon completion, strcasecmp() shall return an integer greater than, equal to, or less than
       0,  if the string pointed to by s1 is, ignoring case, greater than, equal to, or less than
       the string pointed to by s2, respectively.

       Upon successful completion, strncasecmp() shall return an integer greater than, equal  to,
       or  less than 0, if the possibly null-terminated array pointed to by s1 is, ignoring case,
       greater than, equal to, or less than the possibly null-terminated array pointed to by  s2,
       respectively.
