d263a633 EZ |
2341 | |
2342 | System messages are read and processed by w32_msg_pump below. This | |
2343 | function runs in a separate thread. It handles a small number of | |
2344 | custom WM_EMACS_* messages (posted by the main thread, look for | |
2345 | PostMessage calls), and dispatches the rest to w32_wnd_proc, which | |
2346 | is the main window procedure for the entire Emacs application. | |
2347 | ||
2348 | w32_wnd_proc also runs in the same separate input thread. It | |
2349 | handles some messages, mostly those that need GDI calls, by itself. | |
2350 | For the others, it calls my_post_msg, which inserts the messages | |
2351 | into the input queue serviced by w32_read_socket. | |
2352 | ||
2353 | w32_read_socket runs in the main (a.k.a. "Lisp") thread, and is | |
2354 | called synchronously from keyboard.c when it is known or suspected | |
2355 | that some input is available. w32_read_socket either handles | |
17917e74 EZ |
2356 | messages immediately, or converts them into Emacs input events and |
2357 | stuffs them into kbd_buffer, where kbd_buffer_get_event can get at | |
2358 | them and process them when read_char and its callers require | |
36a305a7 DC |
2359 | input. |
2360 | ||
2361 | Under Cygwin with the W32 toolkit, the use of /dev/windows with | |
2362 | select(2) takes the place of w32_read_socket. | |

6380 | operations: | |
6381 | ||
6382 | \"open\" - open DOCUMENT, which could be a file, a directory, or an | |
6383 | executable program. If it is an application, that | |
6384 | application is launched in the current buffer's default | |
6385 | directory. Otherwise, the application associated with | |
6386 | DOCUMENT is launched in the buffer's default directory. | |
6387 | \"print\" - print DOCUMENT, which must be a file | |
6388 | \"explore\" - start the Windows Explorer on DOCUMENT | |
6389 | \"edit\" - launch an editor and open DOCUMENT for editing; which | |
6390 | editor is launched depends on the association for the | |
6391 | specified DOCUMENT | |
6392 | \"find\" - initiate search starting from DOCUMENT which must specify | |
6393 | a directory | |
6394 | nil - invoke the default OPERATION, or \"open\" if default is | |
6395 | not defined or unavailable | |
6396 | ||
6397 | DOCUMENT is typically the name of a document file or a URL, but can | |
6398 | also be a program executable to run, or a directory to open in the | |
6399 | Windows Explorer. | |
6400 | ||
02b39a28 JB |
6401 | If DOCUMENT is a program executable, the optional third arg PARAMETERS |
6402 | can be a string containing command line parameters that will be passed | |
6403 | to the program; otherwise, PARAMETERS should be nil or unspecified. | |
1dccd454 | 6404 | |
02b39a28 | 6405 | Optional fourth argument SHOW-FLAG can be used to control how the |
1dccd454 | 6406 | application will be displayed when it is invoked. If SHOW-FLAG is nil |
