REQUEST ARGUMENTS
- conn
- The XCB connection to X11.
- max_names
- The maximum number of fonts to be returned.
- pattern_len
- The length (in bytes) of pattern.
- pattern
- A font pattern, for example “-misc-fixed-*”.
The asterisk (*) is a wildcard for any number of characters. The question mark (?) is a wildcard for a single character. Use of uppercase or lowercase does not matter.
REPLY FIELDS
- response_type
- The type of this reply, in this case XCB_LIST_FONTS_WITH_INFO. This field is also present in the xcb_generic_reply_t and can be used to tell replies apart from each other.
- sequence
- The sequence number of the last request processed by the X11 server.
- length
- The length of the reply, in words (a word is 4 bytes).
- name_len
- The number of matched font names.
- min_bounds
- minimum bounds over all existing char
- max_bounds
- maximum bounds over all existing char
- min_char_or_byte2
- first character
- max_char_or_byte2
- last character
- default_char
- char to print for undefined character
- properties_len
- how many properties there are
- draw_direction
- One of the following values:
- XCB_FONT_DRAW_LEFT_TO_RIGHT
- TODO: NOT YET DOCUMENTED.
- XCB_FONT_DRAW_RIGHT_TO_LEFT
- TODO: NOT YET DOCUMENTED.
- min_byte1
- TODO: NOT YET DOCUMENTED.
- max_byte1
- TODO: NOT YET DOCUMENTED.
- all_chars_exist
- flag if all characters have nonzero size
- font_ascent
- baseline to top edge of raster
- font_descent
- baseline to bottom edge of raster
- replies_hint
- An indication of how many more fonts will be returned. This is only a hint and may be larger or smaller than the number of fonts actually returned. A zero value does not guarantee that no more fonts will be returned.
DESCRIPTION
Gets a list of available font names which match the given pattern.
RETURN VALUE
Returns an xcb_list_fonts_with_info_cookie_t. Errors have to be handled when calling the reply function xcb_list_fonts_with_info_reply.
If you want to handle errors in the event loop instead, use xcb_list_fonts_with_info_unchecked. See xcb-requests(3) for details.
ERRORS
This request does never generate any errors.
