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. SEE ALSO AUTHOR Generated from glx.xml. Contact xcb@lists.freedesktop.org for correc- tions and improvements. X Version 11 libxcb 1.17.0 xcb_glx_get_histogram(3)
