.Sh SYNOPSIS
|
|
.In string.h
|
|
.Ft int
|
|
.Fn strcoll "const char *s1" "const char *s2"

|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn strcoll
|
|
function
|
|
lexicographically compares the null-terminated strings
|
|
.Fa s1
|
|
and
|
|
.Fa s2
|
|
according to the current locale collation
|
|
and returns an integer greater than, equal to, or less than 0,
|
|
depending on whether
|
|
.Fa s1
|
|
is greater than, equal to, or less than
|
|
.Fa s2 .
|
|
If information about the current locale collation is not available,
|
|
the value of
|
|
.Fn strcmp s1 s2
|
|
is returned.
|
|
The
|
|
.Fn strcoll_l
|
|
function uses an explicit locale argument rather than the system locale.
