Reply Fields

response_type
                 The  type  of this reply, in this case XCB_GLX_GET_HISTOGRAM. 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).

       width     TODO: NOT YET DOCUMENTED.

Request Arguments

conn      The XCB connection to X11.

       context_tag
                 TODO: NOT YET DOCUMENTED.

       target    TODO: NOT YET DOCUMENTED.

       format    TODO: NOT YET DOCUMENTED.

       type      TODO: NOT YET DOCUMENTED.

       swap_bytes
                 TODO: NOT YET DOCUMENTED.

       reset     TODO: NOT YET DOCUMENTED.

Return Value

       Returns an xcb_glx_get_histogram_cookie_t. Errors have to be handled  when  calling  the  reply  function
       xcb_glx_get_histogram_reply.

       If  you want to handle errors in the event loop instead, use xcb_glx_get_histogram_unchecked. See xcb-re‐quests(3) for details.
