KbdClose

(KbdHandle)

KbdHandle (HKBD) - input

Default keyboard or the logical keyboard.
rc (USHORT) - return

  ERROR_KBD_INVALID_HANDLE
  464
  ERROR_KBD_DETACHED

  Remarks

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

  KbdGetFocus

  Wait until focus available on handle 0.
  KbdClose
  Close a logical keyboard handle.
  KbdClose
  Close another logical keyboard handle.
  KbdClose
  Close still another logical keyboard handle.
  KbdFreeFocus
  Give up the focus on handle 0.
