xcb_glx_get_histogram(3) XCB Requests xcb_glx_get_histogram(3) NAME xcb_glx_get_histogram - SYNOPSIS #include <xcb/glx.h> Request function xcb_glx_get_histogram_cookie_t xcb_glx_get_histogram(xcb_connection_t *conn, xcb_glx_context_tag_t context_tag, uint32_t target, uint32_t format, uint32_t type, uint8_t swap_bytes, uint8_t reset); Reply datastructure typedef struct xcb_glx_get_histogram_reply_t { uint8_t response_type; uint8_t pad0; uint16_t sequence; uint32_t length; uint8_t pad1[8]; int32_t width; uint8_t pad2[12]; } xcb_glx_get_histogram_reply_t; Reply function xcb_glx_get_histogram_reply_t *xcb_glx_get_histogram_reply(xcb_connection_t *conn, xcb_glx_get_histogram_cookie_t cookie, xcb_generic_error_t **e); Reply accessors uint8_t *xcb_glx_get_histogram_data(const xcb_glx_get_histogram_request_t *reply); int xcb_glx_get_histogram_data_length(const xcb_glx_get_histogram_reply_t *reply); xcb_generic_iterator_t xcb_glx_get_histogram_data_end(const xcb_glx_get_histogram_reply_t *reply); 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. 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.
