remote calls and success/fail?

[Joe C. <jo...@sw...>]

Hi Jamie,

I've begun to implement DNS record creation using remote_foreign_call, 
and in an attempt to code 'correctly' from the beginning, I'm trying to 
figure out how to do error checking, or at least some form of 
success/fail checking on the remote call.

Any pointers on how this should be done?  I see that the create_record 
routine (and pretty much all the rest) don't return anything 
explicitly...So I'm guessing this is one of those things that perl 
probably does implicitly in some magical manner, but I'm not real sure 
where to look to figure out the magic.

So, my question is:  Can I check for success/fail on a 
remote_foreign_call?  If so, how?

Thanks!
