[Serusers] writing a module - sr-users

14 Feb 2003


      Hi,
I am trying to write a module for SER. I managed to write a tiny test
module ("hello world") and it compiles fine (the source is attached).
However, I'm not quite sure I fully understood how to execute the
functions defined in the module.
I included the module to sr_modules.c and also a line 'loadmodule' in
the ser.cfg. But how do I actually execute the function in the module
every time a (INVITE) message is received by the server?
The docs couldn't really help ...
Thanks very much!
Regards,
Mario
