Re^2: Bit vector fiddling with Inline C

[oxone]

Thanks for the suggestions! Am familiar with bitwise ops in Perl (and with the vec() function which is also very handy here). To clarify: example code is simplified to illustrate the Perl/C interface which is the nub of the question here - the real Inline C is doing a lot more, such that Perl's bitwise ops and vec() aren't enough.
