REPLY FIELDS response_type The type of this reply, in this case XCB_QUERY_FONT. 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). 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 char_infos_len TODO: NOT YET DOCUMENTED. DESCRIPTION Queries information associated with the font. RETURN VALUE Returns an xcb_query_font_cookie_t. Errors have to be handled when calling the reply function xcb_query_font_reply. If you want to handle errors in the event loop instead, use xcb_query_font_unchecked. See xcb-requests(3) for details. ERRORS This request does never generate any errors.
