| 2411 | before w32_console_read_socket in w32inevt.c.) |
| 2412 | |
| 2413 | System messages are read and processed by w32_msg_pump below. This |
| 2414 | function runs in a separate thread. It handles a small number of |
| 2415 | custom WM_EMACS_* messages (posted by the main thread, look for |
| 2416 | PostMessage calls), and dispatches the rest to w32_wnd_proc, which |
| 2417 | is the main window procedure for the entire Emacs application. |
| 2418 | |
| 2419 | w32_wnd_proc also runs in the same separate input thread. It |
| 2420 | handles some messages, mostly those that need GDI calls, by itself. |
| 2421 | For the others, it calls my_post_msg, which inserts the messages |
| 2422 | into the input queue serviced by w32_read_socket. |
| 2423 | |
| 2424 | w32_read_socket runs in the main (a.k.a. "Lisp") thread, and is |
| 2425 | called synchronously from keyboard.c when it is known or suspected |
| 2426 | that some input is available. w32_read_socket either handles |
| 2427 | messages immediately, or converts them into Emacs input events and |
| 2428 | stuffs them into kbd_buffer, where kbd_buffer_get_event can get at |
| 2429 | them and process them when read_char and its callers require |
| 2430 | input. |
| 2431 | |
| 2432 | Under Cygwin with the W32 toolkit, the use of /dev/windows with |
| 2433 | select(2) takes the place of w32_read_socket. |

| 6863 | This is a wrapper around the ShellExecute system function, which |
| 6864 | invokes the application registered to handle OPERATION for DOCUMENT. |
| 6865 | |
| 6866 | OPERATION is either nil or a string that names a supported operation. |
| 6867 | What operations can be used depends on the particular DOCUMENT and its |
| 6868 | handler application, but typically it is one of the following common |
| 6869 | operations: |
| 6870 | |
| 6871 | \"open\" - open DOCUMENT, which could be a file, a directory, or an |
| 6872 | executable program (application). If it is an application, |
| 6873 | that application is launched in the current buffer's default |
| 6874 | directory. Otherwise, the application associated with |
| 6875 | DOCUMENT is launched in the buffer's default directory. |
| 6876 | \"opennew\" - like \"open\", but instruct the application to open |
| 6877 | DOCUMENT in a new window. |
| 6878 | \"openas\" - open the \"Open With\" dialog for DOCUMENT. |
| 6879 | \"print\" - print DOCUMENT, which must be a file. |
| 6880 | \"printto\" - print DOCUMENT, which must be a file, to a specified printer. |
| 6881 | The printer should be provided in PARAMETERS, see below. |
| 6882 | \"explore\" - start the Windows Explorer on DOCUMENT. |
| 6883 | \"edit\" - launch an editor and open DOCUMENT for editing; which |
| 6884 | editor is launched depends on the association for the |
| 6885 | specified DOCUMENT. |
| 6886 | \"find\" - initiate search starting from DOCUMENT, which must specify |
| 6887 | a directory. |
| 6888 | \"delete\" - move DOCUMENT, a file or a directory, to Recycle Bin. |
| 6889 | \"copy\" - copy DOCUMENT, which must be a file or a directory, into |
| 6890 | the clipboard. |
| 6891 | \"cut\" - move DOCUMENT, a file or a directory, into the clipboard. |
| 6892 | \"paste\" - paste the file whose name is in the clipboard into DOCUMENT, |
| 6893 | which must be a directory. |
| 6894 | \"pastelink\" |
| 6895 | - create a shortcut in DOCUMENT (which must be a directory) |
| 6896 | the file or directory whose name is in the clipboard. |
| 6897 | \"runas\" - run DOCUMENT, which must be an excutable file, with |
| 6898 | elevated privileges (a.k.a. \"as Administrator\"). |
| 6899 | \"properties\" |
| 6900 | - open the property sheet dialog for DOCUMENT. |
| 6901 | nil - invoke the default OPERATION, or \"open\" if default is |
| 6902 | not defined or unavailable. |
| 6903 | |
| 6904 | DOCUMENT is typically the name of a document file or a URL, but can |
| 6905 | also be an executable program to run, or a directory to open in the |
| 6906 | Windows Explorer. If it is a file or a directory, it must be a local |
| 6907 | one; this function does not support remote file names. |
| 6908 | |
| 6909 | If DOCUMENT is an executable program, the optional third arg PARAMETERS |
| 6910 | can be a string containing command line parameters, separated by blanks, |
| 6911 | that will be passed to the program. Some values of OPERATION also require |
| 6912 | parameters (e.g., \"printto\" requires the printer address). Otherwise, |
| 6913 | PARAMETERS should be nil or unspecified. Note that double quote characters |
| 6914 | in PARAMETERS must each be enclosed in 2 additional quotes, as in \"\"\". |
| 6915 | |
