strcoll – compare strings according to current collation

LIBRARY SYNOPSIS DESCRIPTION SEE ALSO STANDARDS

Standard C Library (libc, -lc)

#include <string.h>

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

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

The strcoll() 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, depending on whether s1 is greater than, equal to, or less than s2. If information about the current locale collation is not available, the value of strcmp(s1, s2) is returned. The strcoll_l() function uses an explicit locale argument rather than the system locale.

The strcoll() function conforms to ISO/IEC 9899:1990 ("ISO C90"). The strcoll_l() function conforms to IEEE Std 1003.1-2008 ("POSIX.1").
