2380 before w32_console_read_socket in w32inevt.c.)
2381
2382 System messages are read and processed by w32_msg_pump below. This
2383 function runs in a separate thread. It handles a small number of
2384 custom WM_EMACS_* messages (posted by the main thread, look for
2385 PostMessage calls), and dispatches the rest to w32_wnd_proc, which
2386 is the main window procedure for the entire Emacs application.
2387
2388 w32_wnd_proc also runs in the same separate input thread. It
2389 handles some messages, mostly those that need GDI calls, by itself.
2390 For the others, it calls my_post_msg, which inserts the messages
2391 into the input queue serviced by w32_read_socket.
2392
2393 w32_read_socket runs in the main (a.k.a. "Lisp") thread, and is
2394 called synchronously from keyboard.c when it is known or suspected
2395 that some input is available. w32_read_socket either handles
2396 messages immediately, or converts them into Emacs input events and
2397 stuffs them into kbd_buffer, where kbd_buffer_get_event can get at
2398 them and process them when read_char and its callers require
2399 input.
2400
2401 Under Cygwin with the W32 toolkit, the use of /dev/windows with
2402 select(2) takes the place of w32_read_socket.

6398 This is a wrapper around the ShellExecute system function, which

6401 OPERATION is either nil or a string that names a supported operation.
6402 What operations can be used depends on the particular DOCUMENT and its
6403 handler application, but typically it is one of the following common
6404 operations:
6405
6406 \"open\" - open DOCUMENT, which could be a file, a directory, or an
6407 executable program. If it is an application, that
6408 application is launched in the current buffer's default
6409 directory. Otherwise, the application associated with
6410 DOCUMENT is launched in the buffer's default directory.
6411 \"print\" - print DOCUMENT, which must be a file
6412 \"explore\" - start the Windows Explorer on DOCUMENT
6413 \"edit\" - launch an editor and open DOCUMENT for editing; which
6414 editor is launched depends on the association for the
6415 specified DOCUMENT
6416 \"find\" - initiate search starting from DOCUMENT which must specify
6417 a directory
6418 nil - invoke the default OPERATION, or \"open\" if default is
6419 not defined or unavailable
6420
6421 DOCUMENT is typically the name of a document file or a URL, but can
6422 also be a program executable to run, or a directory to open in the
6423 Windows Explorer.
6424
6425 If DOCUMENT is a program executable, the optional third arg PARAMETERS
6426 can be a string containing command line parameters that will be passed
6427 to the program; otherwise, PARAMETERS should be nil or unspecified.
6428
6429 Optional fourth argument SHOW-FLAG can be used to control how the
6430 application will be displayed when it is invoked. If SHOW-FLAG is nil
6431 or unspecified, the application is displayed normally, otherwise it is
6432 an integer representing a ShowWindow flag:

6435 1 - start normally
6436 3 - start maximized
