strcoll, strcoll_lcompare strings, according to current collation

Standard C Library (libc, -lc)

#include <string.h>

int
strcoll(const char *s1, const char *s2);

#include <string.h>
#include <xlocale.h>

int
strcoll_l(const char *s1, const char *s2, locale_t loc);

The () function lexicographically compares the null-terminated strings s1 and s2 according to the current locale collation and returns an integer greater than, equal to, or less than 0, according as s1 is greater than, equal to, or less than s2. If information about the current locale collation is not available, the value of (s1, s2) is returned.

Although the () function uses the current locale, the () function may be passed a locale directly. See xlocale(3) for more information.
