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.
