d263a633 EZ |
2405 | |
2406 | System messages are read and processed by w32_msg_pump below. This | |
2407 | function runs in a separate thread. It handles a small number of | |
2408 | custom WM_EMACS_* messages (posted by the main thread, look for | |
2409 | PostMessage calls), and dispatches the rest to w32_wnd_proc, which | |
2410 | is the main window procedure for the entire Emacs application. | |
2411 | ||
2412 | w32_wnd_proc also runs in the same separate input thread. It | |
2413 | handles some messages, mostly those that need GDI calls, by itself. | |
2414 | For the others, it calls my_post_msg, which inserts the messages | |
2415 | into the input queue serviced by w32_read_socket. | |
2416 | ||
2417 | w32_read_socket runs in the main (a.k.a. "Lisp") thread, and is | |
2418 | called synchronously from keyboard.c when it is known or suspected | |
2419 | that some input is available. w32_read_socket either handles | |
17917e74 EZ |
2420 | messages immediately, or converts them into Emacs input events and |
2421 | stuffs them into kbd_buffer, where kbd_buffer_get_event can get at | |
2422 | them and process them when read_char and its callers require | |
36a305a7 DC |
2423 | input. |
2424 | ||
2425 | Under Cygwin with the W32 toolkit, the use of /dev/windows with | |

6626 | application is launched in the current buffer's default | |
6627 | directory. Otherwise, the application associated with | |
6628 | DOCUMENT is launched in the buffer's default directory. | |
6629 | \"print\" - print DOCUMENT, which must be a file | |
6630 | \"explore\" - start the Windows Explorer on DOCUMENT | |
6631 | \"edit\" - launch an editor and open DOCUMENT for editing; which | |
6632 | editor is launched depends on the association for the | |
6633 | specified DOCUMENT | |
6634 | \"find\" - initiate search starting from DOCUMENT which must specify | |
6635 | a directory | |
6636 | nil - invoke the default OPERATION, or \"open\" if default is | |
6637 | not defined or unavailable | |
6638 | ||
6639 | DOCUMENT is typically the name of a document file or a URL, but can | |
6640 | also be a program executable to run, or a directory to open in the | |
6641 | Windows Explorer. | |
6642 | ||

02b39a28 | 6647 | Optional fourth argument SHOW-FLAG can be used to control how the |
1dccd454 | 6648 | application will be displayed when it is invoked. If SHOW-FLAG is nil |
