[armedbear-devel] how to redirect format function to a socket stream

[Erik Huelsmann]

Hi Santiago,

Welcome to Armed Bear Common Lisp (and Common Lisp in general)!

I've a socket stream named "socket" in this port and host: 50362 and
> localhost

Maybe the underlying stream wants to optimize the socket writes and keeps
your write buffered for now? In that case, you want to use FORCE-OUTPUT to
make sure all internal buffers get written to the stream.

Hope that helps!

Bye,

Erik.
