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.
