Bobby, C's standard exception handling is through "signals", using
functions setjmp, signal and longjmp.

ILE C also has #pragma exception_handler.

You could also use ILE Condition Handlers - see functions CEEHDLR and
CEEHDLU.

I personally find the #pragma exception_handler to be the easiest to
use, but if you want to learn something that's standard for C, learn
about signals.
