NAME
strcoll, strcoll_l
— compare strings according to
current collation
SYNOPSIS
#include
<string.h>
int
strcoll(const
char *s1, const char
*s2);
int
strcoll_l(const
char *s1, const char
*s2, locale_t
locale);
DESCRIPTION
The
strcoll()
and
strcoll_l()
functions lexicographically compare the NUL-terminated strings
s1 and s2 according to the
current locale collation and return an integer greater than, equal to, or
less than 0, according to whether s1 is greater than,
equal to, or less than s2.
On OpenBSD, they have the same effect as
strcmp(3),
and the global locale, the thread-specific locale, and the
locale argument are ignored. On other operating
systems, results may depend on the LC_CTYPE and
LC_COLLATE locale categories set with
setlocale(3),
uselocale(3), or
newlocale(3).

1003.1-2008 (“POSIX.1”).
HISTORY

since 4.3BSD-Reno, and
