Re: Foreign functions, subprocesses in akcl.
See documentation on defentry and faslink.
The file lsp/littleXlsp.lsp provides a good example.
forking a sub process with associated streams:
There is a file c/run-process.c which is used in some versions eg sun.
You may need to repair something in this, but it gives the basic idea.
If you do fix a bug please send it in.
Function in the SI package:
Execute the command STRING in a subshell and return a two way stream
associated to this. Use si::fp-output-stream to get an associated
output stream or si::fp-input-stream.
Bugs: It does not properly deallocate everything,
so that it will fail if you call it too many times.
