  font_name_list_return)
	 XFontSet font_set;
	 XFontStruct ***font_struct_list_return;
	 char ***font_name_list_return;

  char *XBaseFontNameListOfFontSet(font_set)
	XFontSet font_set;

  char *XLocaleOfFontSet(font_set)
	XFontSet font_set;

  Bool XContextDependentDrawing(font_set)

ARGUMENTS

  font_set  Specifies the font set.

  font_name_list_return
	    Returns the list of font names.

  font_struct_list_return
	    Returns the list of font structs.

DESCRIPTION
  The XFontsOfFontSet function returns a list of one or more XFontStructs and
  font names for the fonts used by the Xmb and Xwc layers, for the given font
  set.	A list of pointers to the XFontStruct structures is returned to
  font_struct_list_return.  A list of pointers to null-terminated, fully
  specified font name strings in the locale of the font set is returned to
  font_name_list_return.  The font_name_list order corresponds to the
  font_struct_list order.  The number of XFontStruct structures and font
  names is returned as the value of the function.

  Because it is not guaranteed that a given character will be imaged using a
  single font glyph, there is no provision for mapping a character or default
  string to the font properties, font ID, or direction hint for the font for
  the character.  The client may access the XFontStruct list to obtain these
  values for all the fonts currently in use.

  Xlib does not guarantee that fonts are loaded from the server at the crea-
  tion of an XFontSet.	Xlib may choose to cache font data, loading it only
  as needed to draw text or compute text dimensions.  Therefore, existence of
  the per_char metrics in the XFontStruct structures in the XFontStructSet is
  undefined.  Also, note that all properties in the XFontStruct structures
  are in the STRING encoding.

  The XFontStruct and font name lists are owned by Xlib and should not be
  modified or freed by the client.  They will be freed by a call to
  XFreeFontSet with the associated XFontSet.  Until freed, their contents
  will not be modified by Xlib.

  The XBaseFontNameListOfFontSet function returns the original base font name
  list supplied by the client when the XFontSet was created.  A null-
  terminated string containing a list of comma-separated font names is
  returned as the value of the function.  White space may appear immediately
  on either side of separating commas.

  If XCreateFontSet obtained an XLFD name from the font properties for the
  font specified by a non-XLFD base name, the XBaseFontNameListOfFontSet
  function will return the XLFD name instead of the non-XLFD base name.

  The base font name list is owned by Xlib and should not be modified or
  freed by the client.	It will be freed by a call to XFreeFontSet with the
  associated XFontSet.	Until freed, its contents will not be modified by
  Xlib.

  The XLocaleOfFontSet function returns the name of the locale bound to the
  specified XFontSet, as a null-terminated string.

  The returned locale name string is owned by Xlib and should not be modified
  or freed by the client.  It may be freed by a call to XFreeFontSet with the
  associated XFontSet.	Until freed, it will not be modified by Xlib.

  The XContextDependentDrawing function returns True if the drawing functions
  implement implicit text directionality or if text drawn with the font_set
  might include context-dependent drawing; otherwise, it returns False.

  The XContextualDrawing function returns True if text drawn with the font
  set might include context-dependent drawing; otherwise, it returns False.

  The XDirectionalDependentDrawing function returns True if the drawing func-
  tions implement implicit text directionality; otherwise, it returns False.
