2455 MS-Windows. (For description of non-GUI input, see the commentary
2456 before w32_console_read_socket in w32inevt.c.)
2458 System messages are read and processed by w32_msg_pump below. This
2459 function runs in a separate thread. It handles a small number of
2460 custom WM_EMACS_* messages (posted by the main thread, look for
2461 PostMessage calls), and dispatches the rest to w32_wnd_proc, which
2462 is the main window procedure for the entire Emacs application.
2464 w32_wnd_proc also runs in the same separate input thread. It
2465 handles some messages, mostly those that need GDI calls, by itself.
2466 For the others, it calls my_post_msg, which inserts the messages
2467 into the input queue serviced by w32_read_socket.
2469 w32_read_socket runs in the main (a.k.a. "Lisp") thread, and is
2470 called synchronously from keyboard.c when it is known or suspected
2471 that some input is available. w32_read_socket either handles
2472 messages immediately, or converts them into Emacs input events and
2473 stuffs them into kbd_buffer, where kbd_buffer_get_event can get at
2474 them and process them when read_char and its callers require
2477 Under Cygwin with the W32 toolkit, the use of /dev/windows with
2478 select(2) takes the place of w32_read_socket.

: /* Get Windows to perform OPERATION on DOCUMENT.
6840 This is a wrapper around the ShellExecute system function, which
6841 invokes the application registered to handle OPERATION for DOCUMENT.
6843 OPERATION is either nil or a string that names a supported operation.
6844 What operations can be used depends on the particular DOCUMENT and its
6845 handler application, but typically it is one of the following common
6848 \"open\" - open DOCUMENT, which could be a file, a directory, or an
6849 executable program (application). If it is an application,
6850 that application is launched in the current buffer's default
6851 directory. Otherwise, the application associated with
6852 DOCUMENT is launched in the buffer's default directory.
6853 \"opennew\" - like \"open\", but instruct the application to open
6854 DOCUMENT in a new window.
6855 \"openas\" - open the \"Open With\" dialog for DOCUMENT.
6856 \"print\" - print DOCUMENT, which must be a file.
6857 \"printto\" - print DOCUMENT, which must be a file, to a specified printer.
6858 The printer should be provided in PARAMETERS, see below.
6859 \"explore\" - start the Windows Explorer on DOCUMENT.
6860 \"edit\" - launch an editor and open DOCUMENT for editing; which
6861 editor is launched depends on the association for the
6863 \"find\" - initiate search starting from DOCUMENT, which must specify
6865 \"delete\" - move DOCUMENT, a file or a directory, to Recycle Bin.
6866 \"copy\" - copy DOCUMENT, which must be a file or a directory, into
6868 \"cut\" - move DOCUMENT, a file or a directory, into the clipboard.
6869 \"paste\" - paste the file whose name is in the clipboard into DOCUMENT,
6870 which must be a directory.
6872 - create a shortcut in DOCUMENT (which must be a directory)
6873 the file or directory whose name is in the clipboard.
6874 \"runas\" - run DOCUMENT, which must be an excutable file, with
6875 elevated privileges (a.k.a. \"as Administrator\").
6877 - open the property sheet dialog for DOCUMENT.
6878 nil - invoke the default OPERATION, or \"open\" if default is
6879 not defined or unavailable.
6881 DOCUMENT is typically the name of a document file or a URL, but can
6882 also be an executable program to run, or a directory to open in the
6883 Windows Explorer. If it is a file or a directory, it must be a local
6884 one; this function does not support remote file names.
6886 If DOCUMENT is an executable program, the optional third arg PARAMETERS
6887 can be a string containing command line parameters, separated by blanks,
6888 that will be passed to the program. Some values of OPERATION also require
6889 parameters (e.g., \"printto\" requires the printer address). Otherwise,
6890 PARAMETERS should be nil or unspecified. Note that double quote characters
6891 in PARAMETERS must each be enclosed in 2 additional quotes, as in \"\"\".
6893 Optional fourth argument SHOW-FLAG can be used to control how the
6894 application will be displayed when it is invoked. If SHOW-FLAG is nil
6895 or unspecified, the application is displayed as if SHOW-FLAG of 10 was
6896 specified, otherwise it is an integer between 0 and 11 representing
6900 1 - start as normal-size window
6901 3 - start in a maximized window
6902 6 - start in a minimized window
6903 10 - start as the application itself specifies; this is the default. */)
