NAME

6       strcasecmp, strncasecmp - compare two strings ignoring case
7

SYNOPSIS

9       #include <strings.h>
10
11       int strcasecmp(const char *s1, const char *s2);
12
13       int strncasecmp(const char *s1, const char *s2, size_t n);
14

DESCRIPTION

16       The  strcasecmp() function compares the two strings s1 and s2, ignoring
17       the case of the characters.  It returns an integer less than, equal to,
18       or  greater than zero if s1 is found, respectively, to be less than, to
19       match, or be greater than s2.
20
21       The strncasecmp() function is similar,  except  it  only  compares  the
22       first n characters of s1.
23

RETURN VALUE

25       The  strcasecmp()  and  strncasecmp()  functions return an integer less
26       than, equal to, or greater than zero  if  s1  (or  the  first  n  bytes
27       thereof)  is  found,  respectively,  to  be  less than, to match, or be
28       greater than s2.
