[OpenSIPS-Users] does lua_exec supports async and launch

[Răzvan Crainea]

No, not fdopen, that will just open a FILE* out of a file descriptor. 
The async mechanism works directly with a file descriptor.
I've quickly checked the lua API, and I couldn't see any mechanisms that 
you could use - in this case, you should probably "simulate" an external 
process that gets "lua jobs" and executes them asynchronously, and 
returns a file descriptor that can be tracked down to see the whether 
the exec completed. I'll have to admit, this doesn't see easy :(.
