2356 before w32_console_read_socket in w32inevt.c.)
2357
2358 System messages are read and processed by w32_msg_pump below. This
2359 function runs in a separate thread. It handles a small number of
2360 custom WM_EMACS_* messages (posted by the main thread, look for
2361 PostMessage calls), and dispatches the rest to w32_wnd_proc, which
2362 is the main window procedure for the entire Emacs application.
2363
2364 w32_wnd_proc also runs in the same separate input thread. It
2365 handles some messages, mostly those that need GDI calls, by itself.
2366 For the others, it calls my_post_msg, which inserts the messages
2367 into the input queue serviced by w32_read_socket.
2368
2369 w32_read_socket runs in the main (a.k.a. "Lisp") thread, and is
2370 called synchronously from keyboard.c when it is known or suspected
2371 that some input is available. w32_read_socket either handles
2372 messages immediately, or converts them into Emacs input events and
2373 stuffs them into kbd_buffer, where kbd_buffer_get_event can get at
2374 them and process them when read_char and its callers require
2375 input.
2376
2377 Under Cygwin with the W32 toolkit, the use of /dev/windows with
2378 select(2) takes the place of w32_read_socket.

6379 OPERATION is either nil or a string that names a supported operation.
6380 What operations can be used depends on the particular DOCUMENT and its
6381 handler application, but typically it is one of the following common
6382 operations:
6383
6384 \"open\" - open DOCUMENT, which could be a file, a directory, or an
6385 executable program. If it is an application, that
6386 application is launched in the current buffer's default
6387 directory. Otherwise, the application associated with
6388 DOCUMENT is launched in the buffer's default directory.
6389 \"print\" - print DOCUMENT, which must be a file
6390 \"explore\" - start the Windows Explorer on DOCUMENT
6391 \"edit\" - launch an editor and open DOCUMENT for editing; which
6392 editor is launched depends on the association for the
6393 specified DOCUMENT
6394 \"find\" - initiate search starting from DOCUMENT which must specify
6395 a directory
6396 nil - invoke the default OPERATION, or \"open\" if default is
6397 not defined or unavailable
6398
6399 DOCUMENT is typically the name of a document file or a URL, but can
6400 also be a program executable to run, or a directory to open in the
6401 Windows Explorer.
6402
6403 If DOCUMENT is a program executable, the optional third arg PARAMETERS
6404 can be a string containing command line parameters that will be passed
6405 to the program; otherwise, PARAMETERS should be nil or unspecified.
6406
6407 Optional fourth argument SHOW-FLAG can be used to control how the
6408 application will be displayed when it is invoked. If SHOW-FLAG is nil
6409 or unspecified, the application is displayed normally, otherwise it is
6410 an integer representing a ShowWindow flag:

6413 1 - start normally
