In anarki there is the function connect-socket, I think it is just what you want (have a look at the end of the ac.scm file, just before thread local vars).
Could be. Right now I'm still using the regular arc2, and am now trying to figure out how to deal with the input of the mud, if I've to make separate threads for reading and writing input, or that I can make use of peekc in some way to figure out when the mud has stopped sending characters to the input port. It is fun though :)
Hmm. still a bit puzzled. I seem able to read (in various ways readc, readline) no problem, but writing to cadr inout doesn't seem to trigger new input from the mud to read.
All of you, thanks for the help so far. I'll tinker on with it later, time for my primary arc project ;).
For the output problem, try flushing the out stream with flush-socket on Anarki or the corresponding flush-output from mzscheme, maybe the output is written to a buffer and there is not enough information to send to force the buffer to be flushed.
peekc hangs when I'm reading the output from telnet, but works fine (returning nil) when I'm reading out the output after the last char from a stored pipe.
In my experience peekc doesn't seem to work properly (i.e. as advertised) at all.
I assume you're doing peekc so that you can do something else while waiting for a character? If that is what you're trying to do, I suggest you use threads:
(first time I work with threads) readmud only reads one character at a time, and I want it to just keep on writing as long as there is data. I'll try to add a thread that calls readmud again the moment it returns something sensible.
Partial success. The reading bit seems to function fine (if slow ;), and I now can use arc while in the background the muds' output is being read, but still cannot write. Did add mzscheme's flush-out (but perhaps in some wrong way. Will look at it during the next work-break ;).
Maybe the problem with peekc is that it tries to read a character from the socket, but the server has yet to write that character, and peekc doesn't return nil because the server hasn't yet closed its output stream, so there is no end-of-file.
