2352 before w32_console_read_socket in w32inevt.c.)
2353
2354 System messages are read and processed by w32_msg_pump below. This
2355 function runs in a separate thread. It handles a small number of
2356 custom WM_EMACS_* messages (posted by the main thread, look for
2357 PostMessage calls), and dispatches the rest to w32_wnd_proc, which
2358 is the main window procedure for the entire Emacs application.
2359
2360 w32_wnd_proc also runs in the same separate input thread. It
2361 handles some messages, mostly those that need GDI calls, by itself.
2362 For the others, it calls my_post_msg, which inserts the messages
2363 into the input queue serviced by w32_read_socket.
2364
2365 w32_read_socket runs in the main (a.k.a. "Lisp") thread, and is
2366 called synchronously from keyboard.c when it is known or suspected
2367 that some input is available. w32_read_socket either handles
2368 messages immediately, or converts them into Emacs input events and
2369 stuffs them into kbd_buffer, where kbd_buffer_get_event can get at
2370 them and process them when read_char and its callers require
2371 input.
2372
2373 Under Cygwin with the W32 toolkit, the use of /dev/windows with
2374 select(2) takes the place of w32_read_socket.

6350 This is a wrapper around the ShellExecute system function, which

6352
6353 OPERATION is either nil or a string that names a supported operation.
6354 What operations can be used depends on the particular DOCUMENT and its
6355 handler application, but typically it is one of the following common
6356 operations:
6357
6358 \"open\" - open DOCUMENT, which could be a file, a directory, or an
6359 executable program. If it is an application, that
6360 application is launched in the current buffer's default
6361 directory. Otherwise, the application associated with
6362 DOCUMENT is launched in the buffer's default directory.
6363 \"print\" - print DOCUMENT, which must be a file
6364 \"explore\" - start the Windows Explorer on DOCUMENT
6365 \"edit\" - launch an editor and open DOCUMENT for editing; which
6366 editor is launched depends on the association for the
6367 specified DOCUMENT
6368 \"find\" - initiate search starting from DOCUMENT which must specify
6369 a directory
6370 nil - invoke the default OPERATION, or \"open\" if default is
6371 not defined or unavailable
6372
6373 DOCUMENT is typically the name of a document file or a URL, but can
6374 also be a program executable to run, or a directory to open in the
6375 Windows Explorer.
6376
6377 If DOCUMENT is a program executable, the optional third arg PARAMETERS
6378 can be a string containing command line parameters that will be passed
6379 to the program; otherwise, PARAMETERS should be nil or unspecified.
6380
6381 Optional fourth argument SHOW-FLAG can be used to control how the
6382 application will be displayed when it is invoked. If SHOW-FLAG is nil
6383 or unspecified, the application is displayed normally, otherwise it is
6384 an integer representing a ShowWindow flag:

6387 1 - start normally
6388 3 - start maximized
