XFontsOfFontSet(3X) XLIB FUNCTIONS XFontsOfFontSet(3X)
NAME
XFontsOfFontSet - obtain font set information
SYNTAX
int XFontsOfFontSet(font_set, font_struct_list_return, font_name_list_return)
XFontSet font_set;
XFontStruct ***font_struct_list_return;
char ***font_name_list_return;
ARGUMENTS
font_set Specifies the font set.
font_struct_list_return
Returns the list of font structs.
font_name_list_return
Returns the list of font names.
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 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.
