register_readfd, who uses this info?

Hi, I'm trying to add a socket to my sub-agent to allow communications 
with other processes.

I have called register_readfd(). Looking at the code for 
register_readfd() I see that it stores my callback in 
external_readfdfunc[i]().

The only place I can find that reads external_readfdfunc is in snmpd.c 
receive(). Do I need to copy this code into my sub-agent?

Looking back through old posts I found:

But agent_check_and_process() doesn't read external_readfunc or any of 
the other information stored in register_readfd. What is the recommended 
method for servicing my socket that is registered with register_readfd.
