[Ecls-list] Callbacks from unknown foreign threads

[Luke Crook]

Does ECL handle callbacks from unknown foreign threads? I'm trying to implement 
an audio mixer on top of SDL. The SDL.dll creates a dedicated thread to handle 
audio, and this thread calls back into the Lisp process for audio data. This is 
supported in Lispworks but not in SBCL or CLISP (I think). I believe Corman 
Lisp has a mechanism to bless foreign threads not directly created by the Lisp 
envirnment. Does ECL have anything similar?

Thanks,
