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
17917e74
EZ		 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
36a305a7
DC		 2399 input.
2400

EZ		 6383OPERATION is either nil or a string that names a supported operation.
6384What operations can be used depends on the particular DOCUMENT and its
6385handler application, but typically it is one of the following common
6386operations:
6387
6388 \"open\" - open DOCUMENT, which could be a file, a directory, or an
6389 executable program. If it is an application, that
6390 application is launched in the current buffer's default
6391 directory. Otherwise, the application associated with
6392 DOCUMENT is launched in the buffer's default directory.
6393 \"print\" - print DOCUMENT, which must be a file
6394 \"explore\" - start the Windows Explorer on DOCUMENT
6395 \"edit\" - launch an editor and open DOCUMENT for editing; which
6396 editor is launched depends on the association for the
6397 specified DOCUMENT
6398 \"find\" - initiate search starting from DOCUMENT which must specify
6399 a directory
6400 nil - invoke the default OPERATION, or \"open\" if default is
6401 not defined or unavailable
6402
6403DOCUMENT is typically the name of a document file or a URL, but can
6404also be a program executable to run, or a directory to open in the
6405Windows Explorer.
6406
02b39a28
JB		 6407If DOCUMENT is a program executable, the optional third arg PARAMETERS
6408can be a string containing command line parameters that will be passed
6409to the program; otherwise, PARAMETERS should be nil or unspecified.
1dccd454 6410
02b39a28 6411Optional fourth argument SHOW-FLAG can be used to control how the
1dccd454 6412application will be displayed when it is invoked. If SHOW-FLAG is nil
02b39a28 6413or unspecified, the application is displayed normally, otherwise it is
