Do I need to disconnect an xcb_connection_t that I got from XGetXCBConnection?

Вопрос

Here's an example I saw for some GLX code:

display = XOpenDisplay(0);
// ...
xcb_connection_t *connection = XGetXCBConnection(display);
// ...
XCloseDisplay(display);

I noticed that there was no xcb_disconnect in there. Is this correct? Also, is connection still valid after the display is closed?

Это было полезно?

Решение

XCloseDisplay seems to undo the creation of the display (hence destroying it), and since the XCB connection object is derived from the display, it would seem reasonable that the connection becomes invalidated once the display is closed.
