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 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);

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.
