86                 server.
87
88       length    The length of the reply, in words (a word is 4 bytes).
89
90       name_len  The number of matched font names.

100
101       max_char_or_byte2
102                 last character
103
104       default_char
105                 char to print for undefined character
106
107       properties_len

111                 One of the following values:
112
113                 XCB_FONT_DRAW_LEFT_TO_RIGHT
114                           TODO: NOT YET DOCUMENTED.
115
116                 XCB_FONT_DRAW_RIGHT_TO_LEFT

121       min_byte1 TODO: NOT YET DOCUMENTED.
122
123       max_byte1 TODO: NOT YET DOCUMENTED.
124
125       all_chars_exist
126                 flag if all characters have nonzero size
127
128       font_ascent
129                 baseline to top edge of raster
130
131       font_descent
132                 baseline to bottom edge of raster
133
134       replies_hint
135                 An indication of how many more fonts will be returned. This
136                 is only a hint and may be larger or smaller than the number
137                 of fonts actually returned. A zero value does not guarantee
138                 that no more fonts will be returned.
139

DESCRIPTION

141       Gets a list of available font names which match the given pattern.
142

RETURN VALUE

144       Returns an xcb_list_fonts_with_info_cookie_t. Errors have to be handled
145       when calling the reply function xcb_list_fonts_with_info_reply.
146
147       If you want to handle errors in the event loop instead, use
148       xcb_list_fonts_with_info_unchecked. See xcb-requests(3) for details.
