Emacs can accept input from any KBOARD, - and as soon as any of them provides a complete command, Emacs can run it. - - ** Single kboard. Then Emacs is running a command for one KBOARD - and can only read input from that KBOARD. - - All input, from all KBOARDs, goes together in a single event queue - at interrupt level. read_char sees the events sequentially, - but deals with them in accord with the current input state. - - In the any-kboard state, read_key_sequence processes input from any KBOARD - immediately. When a new event comes in from a particular KBOARD, - read_key_sequence switches to that KBOARD. As a result, - as soon as a complete key arrives from some KBOARD or other, - Emacs starts executing that key's binding. It switches to the - single-kboard state for the execution of that command, - so that that command can get input only from its own KBOARD. - - While in the single-kboard state, read_char can consider input only - from the current KBOARD. If events come from other KBOARDs, they - are put aside for later in the KBOARDs' kbd_queue lists. - The flag kbd_queue_has_data in a KBOARD is 1 if this has happened. - When Emacs goes back to the any-kboard state, it looks at all the KBOARDS - to find those; and it tries processing their input right away. */ - -typedef struct kboard KBOARD; -struct kboard - { - KBOARD *next_kboard; - - /* If non-nil, a keymap that overrides all others but applies only to - this KBOARD.
