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.
ENVIRONMENT
On other operating systems, the behaviour of
strcoll() may depend on the
LC_CTYPE
locale(1).
SEE ALSO
newlocale(3), setlocale(3), strcmp(3), strxfrm(3), wcscoll(3)
STANDARDS

ANSI X3.159-1989 (“ANSI C89”),
and strcoll_l() to IEEE Std
1003.1-2008 (“POSIX.1”).
HISTORY
The strcoll() function has been available
since 4.3BSD-Reno, and
strcoll_l() since OpenBSD
