Re: [Chicken-users] example from rpc egg crashes at around 2k calls for me ....

2015-12-10 Thread Jim Ursetto 
It would coincide with a typical fd ulimit of 2048.  If the issue is actually 
too many tcp connections, I can't see why, as both the client and server should 
close the connection after completion. And, you are running these client 
connections serially. Maybe try dummying out the database calls. I think Peter 
is right that it's trying to serialize a database exception and failing. One 
option would be to handle the db open or query exception yourself in your 
server and print out the exception (before reraising it).

It is absolutely possible, this manual section should help you:
http://wiki.call-cc.org/man/4/Interface%20to%20external%20functions%20and%20variables

and in particular this page: http://wiki.call-cc.org/man/4/Embedding
which explains the CHICKEN C API.

[Chicken-users] shared library for c

2015-12-10 Thread Joe Python 
Is it possible write a shared library in Chicken, say, "libfactorial.a"
which can be called from a C main program?

IF then where is the documentation?

Thank you,
Jo
