4.6 Windows Limitations

• File paths with both `/' and `\' as separator are accepted. SICStus returns paths using `/'. Note that `\', since it is escape character, must be given as `\\'.
• All file names and paths are normalized when expanded by absolute_file_name/3. This is to simulate the case insensitivity used by Windows file systems. This means that files created by SICStus may have names on disk that differs in case from what was specified when the file was created.
• Emacs Issues: Running under Emacs has been tried with recent versions of GNU Emacs and XEmacs. See The Emacs Interface.
  • In both GNU Emacs and XEmacs C-c C-c (comint-interrupt-subprocess) will not interrupt a blocking read from standard input. The interrupt will be noted as soon as some character is sent to SICStus. The characters typed will not be discarded but will instead be used as debugger commands, sometimes leading to undesirable results.
  • Choosing `Send EOF' from the menu, i.e. comint-send-eof), closes the connection to the SICStus process. This will cause SICStus to exit. This problem cannot be fixed in SICStus; it is a limitation of current versions of FSF Emacs and XEmacs (at least up to FSF Emacs 20.7 and XEmacs 21.5).

    Instead of sending and end of file, you can enter the symbol end_of_file followed by a period. Alternatively, a C-z can be generated by typing C-q C-z.

• Under Windows, statistics(runtime, ...) measures user time of the thread running SICStus (the main thread) instead of process user time. This makes statistics(runtime, ...) meaningful also in a multi-threaded program.
