# strcoll\_l(3)

compare strings according to current collation

Part of [strcoll(3)](/strcoll/3.md).

## NAME

**strcoll** – compare strings according to current collation

## LIBRARY

Standard C Library (libc, -lc)

## SYNOPSIS

**#include \<string.h\>**

*int*\

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

*int*\

**strcoll\_l**(*const char \*s1*, *const char \*s2*, *locale\_t loc*);

## DESCRIPTION

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.

## SEE ALSO

[setlocale(3)](/setlocale/3.md), [strcmp(3)](/strcmp/3.md), [strxfrm(3)](/strxfrm/3.md), [wcscoll(3)](/wcscoll/3.md)

## STANDARDS

The **strcoll**() function conforms to ISO/IEC 9899:1990 (“ISO C90”). The **strcoll\_l**() function conforms to IEEE Std 1003.1-2008 (“POSIX.1”).
