@param c The connection
@param revert_to A bitmask of #xcb_input_focus_t values.
@param revert_to Specifies what happens when the \a focus window becomes unviewable (if \a focus
is neither XCB_NONE nor XCB_POINTER_ROOT).
@param focus The window to focus. All keyboard events will be reported to this window. The
window must be viewable (TODO), or a xcb_match_error_t occurs (TODO).
\n
If \a focus is XCB_NONE (TODO), all keyboard events are
discarded until a new focus window is set.
\n
If \a focus is XCB_POINTER_ROOT (TODO), focus is on the root window of the
screen on which the pointer is on currently.
@param time Timestamp to avoid race conditions when running X over the network.
\n
The special value XCB_CURRENT_TIME will be replaced with the current server
time.
@return A cookie
Changes the input focus and the last-focus-change time. If the specified \a time
is earlier than the current last-focus-change time, the request is ignored (to
avoid race conditions when running X over the network).
A FocusIn and FocusOut event is generated when focus is changed.
