2426 custom WM_EMACS_* messages (posted by the main thread, look for
2427 PostMessage calls), and dispatches the rest to w32_wnd_proc, which
2428 is the main window procedure for the entire Emacs application.
2430 w32_wnd_proc also runs in the same separate input thread. It
2431 handles some messages, mostly those that need GDI calls, by itself.
2432 For the others, it calls my_post_msg, which inserts the messages
2433 into the input queue serviced by w32_read_socket.
2435 w32_read_socket runs in the main (a.k.a. "Lisp") thread, and is
2436 called synchronously from keyboard.c when it is known or suspected
2437 that some input is available. w32_read_socket either handles
2438 messages immediately, or converts them into Emacs input events and
2439 stuffs them into kbd_buffer, where kbd_buffer_get_event can get at
2440 them and process them when read_char and its callers require
2443 Under Cygwin with the W32 toolkit, the use of /dev/windows with
2444 select(2) takes the place of w32_read_socket.

6830 This is a wrapper around the ShellExecute system function, which
6831 invokes the application registered to handle OPERATION for DOCUMENT.
6833 OPERATION is either nil or a string that names a supported operation.
6834 What operations can be used depends on the particular DOCUMENT and its
6835 handler application, but typically it is one of the following common
6838 \"open\" - open DOCUMENT, which could be a file, a directory, or an
6839 executable program. If it is an application, that
6840 application is launched in the current buffer's default
6841 directory. Otherwise, the application associated with
6842 DOCUMENT is launched in the buffer's default directory.
6843 \"print\" - print DOCUMENT, which must be a file
6844 \"explore\" - start the Windows Explorer on DOCUMENT
6845 \"edit\" - launch an editor and open DOCUMENT for editing; which
6846 editor is launched depends on the association for the
6848 \"find\" - initiate search starting from DOCUMENT which must specify
6850 \"runas\" - run DOCUMENT, which must be an excutable file, with
6851 elevated privileges (a.k.a. \"as Administrator\").
6852 nil - invoke the default OPERATION, or \"open\" if default is
6853 not defined or unavailable
6855 DOCUMENT is typically the name of a document file or a URL, but can
6856 also be a program executable to run, or a directory to open in the
6857 Windows Explorer. If it is a file, it must be a local one; this
6858 function does not support remote file names.
6860 If DOCUMENT is a program executable, the optional third arg PARAMETERS
6861 can be a string containing command line parameters that will be passed
6862 to the program; otherwise, PARAMETERS should be nil or unspecified.
6864 Optional fourth argument SHOW-FLAG can be used to control how the
6865 application will be displayed when it is invoked. If SHOW-FLAG is nil
6866 or unspecified, the application is displayed normally, otherwise it is
6867 an integer representing a ShowWindow flag:
