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. 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).
names_len: The number of font names.

DESCRIPTION

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

RETURN VALUE

Returns an xcb_list_fonts_cookie_t. Errors have to be handled when calling the reply function xcb_list_fonts_reply.

If you want to handle errors in the event loop instead, use xcb_list_fonts_unchecked. See xcb-requests(3) for details.

ERRORS
