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.
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.
DESCRIPTION
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-requests(3) for details.
ERRORS
This request does never generate any errors.
