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.

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.

Gets a list of available font names which match the given pattern.

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.

This request does never generate any errors.
