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 function returns a list of one or more and font names for the fonts
used by the Xmb and Xwc layers, for the given font set. A list of
pointers to the 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 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 list to
obtain these values for all the fonts currently in use.
It is not required that fonts be loaded from the server at the creation
of an 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 structures in the is undefined. Also, note
that all properties in the structures are in the STRING encoding.
The 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 with the associ‐
ated Until freed, its contents will not be modified by Xlib.
The function returns the original base font name list supplied by the
client when the was created. A null-terminated string containing a
list of comma-separated font names is returned as the value of the
function. Whitespace may appear immediately on either side of separat‐
ing commas.
If obtained an XLFD name from the font properties for the font speci‐
fied by a non-XLFD base name, the 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 with the associated
Until freed, its contents will not be modified by Xlib.
The function returns the name of the locale bound to the specified 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 with the
associated Until freed, it will not be modified by Xlib.
The function returns if text drawn with the font_set might include con‐
text-dependent drawing.
