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 lay-
       ers 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 charac-
       ter 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
       creation 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 con-
       tents 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 XBaseFontNameListOf-
       FontSet 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 modi-
       fied 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 XFree-
       FontSet 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
       functions implement implicit text directionality; otherwise, it
       returns False.
