2356 MS-Windows. (For description of non-GUI input, see the commentary
2357 before w32_console_read_socket in w32inevt.c.)
2359 System messages are read and processed by w32_msg_pump below. This
2360 function runs in a separate thread. It handles a small number of
2361 custom WM_EMACS_* messages (posted by the main thread, look for
2362 PostMessage calls), and dispatches the rest to w32_wnd_proc, which
2363 is the main window procedure for the entire Emacs application.
2365 w32_wnd_proc also runs in the same separate input thread. It
2366 handles some messages, mostly those that need GDI calls, by itself.
2367 For the others, it calls my_post_msg, which inserts the messages
2368 into the input queue serviced by w32_read_socket.
2370 w32_read_socket runs in the main (a.k.a. "Lisp") thread, and is
2371 called synchronously from keyboard.c when it is known or suspected
2372 that some input is available. w32_read_socket either handles
2373 messages immediately, or converts them into Emacs input events and
2374 stuffs them into kbd_buffer, where kbd_buffer_get_event can get at
2375 them and process them when read_char and its callers require
2378 Under Cygwin with the W32 toolkit, the use of /dev/windows with
2379 select(2) takes the place of w32_read_socket.

5680 DY added (default is -10).

6393 \"explore\" - start the Windows Explorer on DOCUMENT
6394 \"edit\" - launch an editor and open DOCUMENT for editing; which
6395 editor is launched depends on the association for the
6397 \"find\" - initiate search starting from DOCUMENT which must specify
6399 nil - invoke the default OPERATION, or \"open\" if default is
6400 not defined or unavailable
