DESCRIPTION

RETURN VALUE

76       Returns an xcb_glx_get_histogram_cookie_t. Errors have to be handled
77       when calling the reply function xcb_glx_get_histogram_reply.
78
79       If you want to handle errors in the event loop instead, use
80       xcb_glx_get_histogram_unchecked. See xcb-requests(3) for details.
