[PD] exiting function in external

[Jaime E Oliver via Pd-list]

Hi all, 

I am writing a long and complex external. 

There are several conditions in which a particular function could fail and in any of those cases I'd like to report the error and stop the execution of the function.

I tried using the exit() function, but that quits pd, and what I really need is for the function to simply stop.

Does pd have a function for doing this?

best,

J
