Remarks

KbdOpen blocks while another thread has the keyboard focus (by way of KbdGetFocus) until the thread with the focus issues KbdFreeFocus. Therefore, to prevent KbdOpen from blocking, it is recommended that KbdOpen be issued only while the current thread has the focus. For example:

KbdGetFocus wait until focus available on handle 0 KbdOpen get a logical keyboard handle KbdOpen get another logical keyboard handle KbdOpen get yet another logical keyboard handle KbdFreeFocus give up the focus on handle 0.
