.Sh DESCRIPTION
The
.Fn strcoll
function
lexicographically compares the null-terminated strings
.Fa s1
and
.Fa s2 ,
according to the current locale collation, if any.
Otherwise, it calls
.Fa strcmp
and returns an integer greater than, equal to, or less than 0,
according as
.Fa s1
is greater than, equal to, or less than
.Fa s2 .
.Pp
Although the
.Fn strcoll
function uses the current locale, the
.Fn strcoll_l
function may be passed a locale directly. See
.Xr xlocale 3
for more information.
