NAME
       XFontsOfFontSet,	XBaseFontNameListOfFontSet, XLocaleOfFontSet, XCon-
       textDependentDrawing, XContextualDrawing, XDirectionalDependentDrawing
       - obtain	fontset	information

SYNTAX
       int XFontsOfFontSet(XFontSet font_set, XFontStruct
	      ***font_struct_list_return, char ***font_name_list_return);

       char *XBaseFontNameListOfFontSet(XFontSet font_set);

       char *XLocaleOfFontSet(XFontSet font_set);

       Bool XContextDependentDrawing(XFontSet font_set);

       Bool XContextualDrawing(XFontSet	font_set);

       Bool XDirectionalDependentDrawing(XFontSet 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-termi-
       nated, fully specified font name	strings	in the locale of the font set
       is returned to font_name_list_return.  The font_name_list order corre-
       sponds to the font_struct_list order.  The number of XFontStruct	struc-
       tures 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 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 imme-
       diately 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 mod-
       ified 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 mod-
       ified by	Xlib.

       The XContextDependentDrawing function returns True if the drawing func-
       tions 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.
