View Ref-File13.14.1.3.4  The info call (xfsl_info)                             TOS

With this call one can inquire about some of the features of the 
installed font-selector:

     long xfsl_info (void);

If the return value is positive, then the following flags represent 
the features that are present (negative return values are, as usual, 
error-messages):

      Name         Value   Meaning 
      XF_SIZE      0x0001  Size changes possible 
      XF_COLOR     0x0002  Colour changes possible 
      XF_ATTR      0x0004  Attribute changes possible 
      XF_WIDTH     0x0008  Width changes possible 
      XF_KERN      0x0010  Kerning changes possible 
      XF_SKEW      0x0020  Slope/skew changes possible 
      XF_ALIGN     0x0040  Alignment changes possible 
      XF_ROTATION  0x0080  Text rotation possible 
      XF_FIX31     0x0100  fix31 support 
      XF_POPUP     0x0200  Popup support 
      XF_DRAGDROP  0x0400  Drag&Drop support 
      XF_MAPPING   0x0800  Understands mapping 

Further features of the font-selector can be inquired indirectly via 
the control element of the xFSL_PAR structure: On a successful 
xfsl_init call, those control-flags that the font-selector does not 
know are cleared.
