NAME

6       strcasecmp, strncasecmp - case-insensitive string comparisons
7

SYNOPSIS

9       #include <strings.h>
10
11       int strcasecmp(const char *s1, const char *s2);
12       int strncasecmp(const char *s1, const char *s2, size_t n);

DESCRIPTION

16       The  strcasecmp() function shall compare, while ignoring differences in
17       case, the string pointed to by s1 to the string pointed to by  s2.  The
18       strncasecmp()  function  shall  compare,  while ignoring differences in
19       case, not more than n bytes from the string pointed to  by  s1  to  the
20       string pointed to by s2.
21
22       In  the POSIX locale, strcasecmp() and strncasecmp() shall behave as if
23       the strings had been converted to lowercase and then a byte  comparison
24       performed. The results are unspecified in other locales.
25

RETURN VALUE

27       Upon  completion,  strcasecmp()  shall  return an integer greater than,
28       equal to, or less than 0, if the string pointed to by s1  is,  ignoring
29       case, greater than, equal to, or less than the string pointed to by s2,
30       respectively.
31
32       Upon successful  completion,  strncasecmp()  shall  return  an  integer
33       greater than, equal to, or less than 0, if the possibly null-terminated
34       array pointed to by s1 is, ignoring case, greater than,  equal  to,  or
35       less  than the possibly null-terminated array pointed to by s2, respec‐
36       tively.
