C has no clue about the exception, so you can neither catch it in C nor have C relay it to the original Perl context. The error is, not very clearly (or rather, saying it clearly but in terms of internals), saying this: it can't find an exception handler in the callback's Perl context (and, implicitly, it can never reach one outside of the callback's context). Distilling this down to a short error message is a bit difficult. -- brandon s allbery kf8nh sine nomine associates allber...@gmail.com ballb...@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
