Hello,
this is my first attempt to add:
- handler for SIGTERM
- make rxapi capable of working with the AIX subsystem resource
controller (SRC)
I had added some debugging output to the Stop() routine during my tests.
The apiServer.terminateServer() gets called and then exit(1) gets called.
So it can't be completely wrong :-))
Index: APIService.cpp / not checked with Linux ... I would need a
volunteer for that :-)
