NAME
    OpenScreenTagList -- OpenScreen() with TagItem extension array. (V36)
    OpenScreenTags -- Varargs stub for OpenScreenTagList. (V36)

SYNOPSIS
    Screen = OpenScreenTagList( NewScreen, TagItems )
    D0                          A0         A1

    struct Screen *OpenScreenTagList( struct NewScreen *,
            struct TagItem * );

    Screen = OpenScreenTags( NewScreen, Tag1, ... )

    struct Screen *OpenScreenTags( struct NewScreen *,
            ULONG, ... );

FUNCTION
    Provides an extension to the parameters passed to OpenScreen().
    This extensions is in the form of (a pointer to) an array of
    TagItem structures, which have to fields: ti_Tag, an ID identifying
    the meaning of the other field, ti_Data.  See <utility/tagitem.h>.

    The tag items can supplement or override the values in NewScreen.
    In fact, you can pass a NULL value of the NewScreen pointer.
    For that matter, if you pass NULL in both arguments, you'll get
    a screen with defaults in all fields, including display mode,
    depth, colors, dimension, title, and so on.  We ask that
    you at least supply a title when you open a screen.

    See OpenScreen() documentation for parameter specifications.

INPUTS
    NewScreen     - (optional) pointer to a NewScreen structure.
    TagItems      - (optional) pointer to (an array of) TagItem
                    structures, terminated by the value TAG_END.

RESULT
    Screen     - an open Intuition screen.  See OpenScreen() for
            extended error codes when Screen is returned NULL.

EXAMPLE
    The version using a variable number of arguments must be
    created for each particular compiler, and may not have
    an analogue in all versions.  For vanilla, 32-bit C
    parameter passing conventions, this works (and will
    appear in amiga.lib):

    struct Screen      *
    OpenScreenTags( ns, tag1 )
    struct NewScreen  *ns;
    ULONG                   tag1;
    {
        struct Screen  *OpenScreenTagList();

        return ( OpenScreenTagList( ns, (struct TagItem *) &tag1 ) );
    }

NOTES
    We recommend this extension to OpenScreen() over using the
    field ExtNewScreen.Extension.  However, the ExtNewScreen.Extension
    is a convenient way to supply a few tags to V36 Intuition which
    will be ignored by V34 Intuition.  See OpenScreen() documentation
    for lots of details.
