[clisp-list] How to open file descriptor with CLISP?

[Jean L. <bu...@gn...>]

I am looking into solution to open file descriptor in CLISP, and to
get its fileno, that I can feed files to GNU mailutils, mail program
to file descriptors.

Basically, into functionality that is shown in the sample Perl program
here: http://mailutils.org/wiki/Mail:_sending_attachments -- relating
to opening file descriptor and getting its number.

There is function ext:stream-handles which should be documented in
http://clisp.org/impnotes/stream-handles.html
I have no idea why it is only documented in the beta docs
http://clisp.org/beta/impnotes/stream-handles.html.

There goes my zorkmid. :-(

         An error has been encountered in accessing this page.

         2. URL path: /impnotes/stream-handles.html
         3. Error notes: NONE
         4. Error type: 404

Do you know what happened with it?

As now I am searching again for the documentation.

Works for me

21.18. Function EXT:STREAM-HANDLES

The function (EXT:STREAM-HANDLES stream) returns two values:

The OS file descriptor for the input side of the stream, or NIL if the 
stream is an output-only STREAM or if there is no file descriptor 
associated with it.
The OS file descriptor for the output side of the stream, or NIL if the 
stream is an input-only STREAM or if there is no file descriptor 
associated with it.
Warning

It is dangerous to CLOSE the file descriptors returned by this function. 
This may lead to EBADF OS ERRORs and, eventually, segmentation faults. 
Always use CLOSE on the original Lisp streams instead.

These notes document CLISP version 2.49+
