STRCOLL(3)

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
The strcoll() function conforms to ansiC, and strcoll_l() to p1003.1-2008.

HISTORY
The strcoll() function has been available since 4.3BSD Reno, and strcoll_l() since OpenBSD 6.2.
