SYNOPSIS

#include <xcb/xproto.h>

    Request function

xcb_void_cookie_t xcb_create_gc(xcb_connection_t *conn, xcb_gcontext_t cid, xcb_drawable_t drawable, uint32_t value_mask, const uint32_t *value_list);
 

REQUEST ARGUMENTS

conn The XCB connection to X11.
cid The ID with which you will refer to the graphics context, created by xcb_generate_id.
drawable Drawable to get the root/depth from.
value_mask TODO: NOT YET DOCUMENTED.
value_list TODO: NOT YET DOCUMENTED.

DESCRIPTION

Creates a graphics context. The graphics context can be used with any drawable that has the same root and depth as the specified drawable.

RETURN VALUE

Returns an xcb_void_cookie_t. Errors (if any) have to be handled in the event loop.

If you want to handle errors directly with xcb_request_check instead, use xcb_create_gc_checked. See xcb-requests(3) for details.

ERRORS

xcb_alloc_error_t The X server could not allocate the requested resources (no memory?).
xcb_drawable_error_t The specified drawable (Window or Pixmap) does not exist.
xcb_font_error_t TODO: reasons?
xcb_match_error_t TODO: reasons?
xcb_pixmap_error_t TODO: reasons?
xcb_value_error_t TODO: reasons?
