 _getarcinfo()           Get font characteristics

 #include   <graph.h>

 short _getfontinfo(fontbuffer);
 struct _fontinfo _far *fontbuffer;     _fontinfo variable

    _getfontinfo() returns information about the current font in a
    _fontinfo structure:

                struct _fontinfo
                {
                int  type;
                int  ascent;
                int  pixwidth;
                int  pixheight;
                int  avgwidth;
                char filename[81];
                char facename[32];
                };

    Returns:         Nonzero value for success; -1 otherwise.

    Portability:     MS-DOS only, true MDPA, CGA, EGA, MCGA, or VGA video
                     compatibles

   -------------------------------- Example ---------------------------------

        This program prints out a text string in a font from a .FON file.

    #include <conio.h>
    #include <stdio.h>
    #include <stdlib.h>
    #include <graph.h>

    unsigned char *tstring = "Here is the Text";

    void main()
    {
        struct videoconfig vstruc;
        struct _fontinfo finfo;
        short nfont, maxfonts, halfinx, halfiny;

        _setvideomode(_MAXRESMODE);
        _getvideoconfig(&vstruc);
        _registerfonts("*.FON");
        _clearscreen(_GCLEARSCREEN);

        halfinx = vstruc.numxpixels/2 - _getgtextextent(tstring)/2;
        halfiny = vstruc.numypixels/2 + _getgtextextent(tstring)/2;
        _moveto(halfinx, halfiny);

        _setfont("n1");     /* Display first font */
        _setgtextvector(1, 0);
        _outgtext(tstring);
        _setgtextvector(-1, 0);
        _outgtext(tstring);
        _getfontinfo(&finfo);
        getch();

        _unregisterfonts();
        _setvideomode(_DEFAULTMODE);
    }
