Yes, well, I caught that part.  Thing is, I copied these two lines
from the complex sample code:
  reg_handler(HDLR_KEYS,&keys_handler);
  reg_ontimeout(ontimeout,1000,0);

And the appropriate declarations for those to work (as far as I know
anyway) and neither one is functioning.  That's why I asked in here. 
Both seem to fit that criteria mentioned earlier.  I'm probably
missing something, but, I'm afraid I don't know what it is.  If it
were as simple as just looking in the manual and automatically
understanding I wouldn't be asking here, and I still hesitated as it
was.
