d263a633 EZ |
2414 | |
2415 | System messages are read and processed by w32_msg_pump below. This | |
2416 | function runs in a separate thread. It handles a small number of | |
2417 | custom WM_EMACS_* messages (posted by the main thread, look for | |
2418 | PostMessage calls), and dispatches the rest to w32_wnd_proc, which | |
2419 | is the main window procedure for the entire Emacs application. | |
2420 | ||
2421 | w32_wnd_proc also runs in the same separate input thread. It | |
2422 | handles some messages, mostly those that need GDI calls, by itself. | |
2423 | For the others, it calls my_post_msg, which inserts the messages | |
2424 | into the input queue serviced by w32_read_socket. | |
2425 | ||
2426 | w32_read_socket runs in the main (a.k.a. "Lisp") thread, and is | |
2427 | called synchronously from keyboard.c when it is known or suspected | |
2428 | that some input is available. w32_read_socket either handles | |
17917e74 EZ |
2429 | messages immediately, or converts them into Emacs input events and |
2430 | stuffs them into kbd_buffer, where kbd_buffer_get_event can get at | |
2431 | them and process them when read_char and its callers require | |
36a305a7 DC |
2432 | input. |
2433 | ||
2434 | Under Cygwin with the W32 toolkit, the use of /dev/windows with | |

74e1aeec | 6849 | |
1dccd454 EZ |
6850 | OPERATION is either nil or a string that names a supported operation. |
6851 | What operations can be used depends on the particular DOCUMENT and its | |
6852 | handler application, but typically it is one of the following common | |
6853 | operations: | |
6854 | ||
6855 | \"open\" - open DOCUMENT, which could be a file, a directory, or an | |
6d48053b EZ |
6856 | executable program (application). If it is an application, |
6857 | that application is launched in the current buffer's default | |
1dccd454 EZ |
6858 | directory. Otherwise, the application associated with |
6859 | DOCUMENT is launched in the buffer's default directory. | |
6d48053b EZ |
6860 | \"opennew\" - like \"open\", but instruct the application to open |
6861 | DOCUMENT in a new window. | |
6862 | \"openas\" - open the \"Open With\" dialog for DOCUMENT. | |
6863 | \"print\" - print DOCUMENT, which must be a file. | |
6864 | \"printto\" - print DOCUMENT, which must be a file, to a specified printer. | |
6865 | The printer should be provided in PARAMETERS, see below. | |
6866 | \"explore\" - start the Windows Explorer on DOCUMENT. | |
1dccd454 EZ |
6867 | \"edit\" - launch an editor and open DOCUMENT for editing; which |
6868 | editor is launched depends on the association for the | |
6d48053b EZ |
6869 | specified DOCUMENT. |
6870 | \"find\" - initiate search starting from DOCUMENT, which must specify | |
6871 | a directory. | |
6d731d41 EZ |
6872 | \"delete\" - move DOCUMENT, a file or a directory, to Recycle Bin. |
6873 | \"copy\" - copy DOCUMENT, which must be a file or a directory, into | |
6874 | the clipboard. | |
6875 | \"cut\" - move DOCUMENT, a file or a directory, into the clipboard. | |
6876 | \"paste\" - paste the file whose name is in the clipboard into DOCUMENT, | |
6877 | which must be a directory. | |
6878 | \"pastelink\" | |
6879 | - create a shortcut in DOCUMENT (which must be a directory) | |
6880 | the file or directory whose name is in the clipboard. | |
ec6e26b8 EZ |
6881 | \"runas\" - run DOCUMENT, which must be an excutable file, with |
6882 | elevated privileges (a.k.a. \"as Administrator\"). | |
6d48053b | 6883 | \"properties\" |
6d731d41 | 6884 | - open the the property sheet dialog for DOCUMENT. |
1dccd454 | 6885 | nil - invoke the default OPERATION, or \"open\" if default is |
6d48053b | 6886 | not defined or unavailable. |
1dccd454 EZ |
6887 | |
6888 | DOCUMENT is typically the name of a document file or a URL, but can | |
6d48053b | 6889 | also be an executable program to run, or a directory to open in the |
6d731d41 EZ |
6890 | Windows Explorer. If it is a file or a directory, it must be a local |
6891 | one; this function does not support remote file names. | |
1dccd454 | 6892 | |
6d48053b | 6893 | If DOCUMENT is an executable program, the optional third arg PARAMETERS |
6d731d41 EZ |
6894 | can be a string containing command line parameters, separated by blanks, |
6895 | that will be passed to the program. Some values of OPERATION also require | |
6896 | parameters (e.g., \"printto\" requires the printer address). Otherwise, | |
6897 | PARAMETERS should be nil or unspecified. Note that double quote characters | |
6898 | in PARAMETERS must each be enclosed in 2 additional quotes, as in \"\"\". | |
1dccd454 | 6899 | |
02b39a28 | 6900 | Optional fourth argument SHOW-FLAG can be used to control how the |
1dccd454 | 6901 | application will be displayed when it is invoked. If SHOW-FLAG is nil |
6d48053b EZ |
6902 | or unspecified, the application is displayed as if SHOW-FLAG of 10 was |
6903 | specified, otherwise it is an integer between 0 and 11 representing | |
6904 | a ShowWindow flag: | |
