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.

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 character 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.

Xlib does not guarantee that fonts are 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 associated Until freed, their 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. White space may appear immediately on either side of separating commas.

If obtained an XLFD name from the font properties for the font specified 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 modified 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 the drawing functions implement implicit text directionality or if text drawn with the font_set might include context-dependent drawing; otherwise, it returns
