-.Sh DESCRIPTION
-The
-.Fn wcscoll
-function compares the null-terminated strings
-.Fa ws1
-and
-.Fa ws2 ,
-according to the current locale's collation order.
-In the
-.Dq Li C
-locale,
-.Fn wcscoll
-is equivalent to
-.Fn wcscmp .
-.Pp
-Although the
-.Fn wcscoll
-function uses the current locale, the
-.Fn wcscoll_l
-function may be passed a locale directly. See
-.Xr xlocale 3
-for more information.
-.Sh RETURN VALUES
-The
-.Fn wcscoll
-function
-returns an integer greater than, equal to, or less than 0,
-if
-.Fa ws1
-is greater than, equal to, or less than
-.Fa ws2 .
-.Pp
-No return value is reserved to indicate errors;
-callers should set
-.Va errno
-to 0 before calling
-.Fn wcscoll .
-If it is non-zero upon return from
-.Fn wcscoll ,
-an error has occurred.
-.Sh ERRORS
-The
-.Fn wcscoll
-function will fail if:
-.Bl -tag -width Er
-.It Bq Er EILSEQ
-An invalid wide character code was specified.
-.It Bq Er ENOMEM
-Cannot allocate enough memory for temporary buffers.

-.Xr strcoll 3 ,
-.Xr wcscmp 3 ,
-.Xr wcsxfrm 3 ,
-.Xr xlocale 3
-.Sh STANDARDS
-The
-.Fn wcscoll
-function
-conforms to
-.St -isoC-99 .
-.Sh BUGS
-The current implementation of
-.Fn wcscoll
-only works in single-byte
-.Dv LC_CTYPE
-locales, and falls back to using
-.Fn wcscmp
-in locales with extended character sets.
