2411 MS-Windows. (For description of non-GUI input, see the commentary
2412 before w32_console_read_socket in w32inevt.c.)
2414 System messages are read and processed by w32_msg_pump below. This
2415 function runs in a separate thread. It handles a small number of
2416 custom WM_EMACS_* messages (posted by the main thread, look for
2417 PostMessage calls), and dispatches the rest to w32_wnd_proc, which
2418 is the main window procedure for the entire Emacs application.
2420 w32_wnd_proc also runs in the same separate input thread. It
2421 handles some messages, mostly those that need GDI calls, by itself.
2422 For the others, it calls my_post_msg, which inserts the messages
2423 into the input queue serviced by w32_read_socket.
2425 w32_read_socket runs in the main (a.k.a. "Lisp") thread, and is
2426 called synchronously from keyboard.c when it is known or suspected

6826 This is a wrapper around the ShellExecute system function, which
6827 invokes the application registered to handle OPERATION for DOCUMENT.
6829 OPERATION is either nil or a string that names a supported operation.
6830 What operations can be used depends on the particular DOCUMENT and its
6831 handler application, but typically it is one of the following common
6834 \"open\" - open DOCUMENT, which could be a file, a directory, or an
6835 executable program. If it is an application, that
6836 application is launched in the current buffer's default
6837 directory. Otherwise, the application associated with
6838 DOCUMENT is launched in the buffer's default directory.
6839 \"print\" - print DOCUMENT, which must be a file
6840 \"explore\" - start the Windows Explorer on DOCUMENT
6841 \"edit\" - launch an editor and open DOCUMENT for editing; which
6842 editor is launched depends on the association for the
6844 \"find\" - initiate search starting from DOCUMENT which must specify
6846 \"runas\" - run DOCUMENT, which must be an excutable file, with
6847 elevated privileges (a.k.a. \"as Administrator\").
6848 nil - invoke the default OPERATION, or \"open\" if default is
6849 not defined or unavailable
6851 DOCUMENT is typically the name of a document file or a URL, but can
6852 also be a program executable to run, or a directory to open in the
6853 Windows Explorer. If it is a file, it must be a local one; this
6854 function does not support remote file names.
6856 If DOCUMENT is a program executable, the optional third arg PARAMETERS
6857 can be a string containing command line parameters that will be passed
6858 to the program; otherwise, PARAMETERS should be nil or unspecified.
6860 Optional fourth argument SHOW-FLAG can be used to control how the
6861 application will be displayed when it is invoked. If SHOW-FLAG is nil
6862 or unspecified, the application is displayed normally, otherwise it is
6863 an integer representing a ShowWindow flag:
