Ruby vec() command equivalent?

ruby-talk
1

In perl I can do this:

vec(expr, offset, bits)

which is needed in non-blocking socket operations for data read and write
selects.

Is there a Ruby equivalent for this?

If not, anyone have a workaround for what vec() does?

Thanks!
Andy

I also wanted to add, that the vec() command in Perl provides the framework
for doing an FD_SET and FD_ZERO in C … Hope that helps, still not sure
about implementing this in Ruby.

Thanks!

You can use

IO::select([fd1, fd2, fd3], [fd4, fd5], nil, timeout)

no vec() is needed. But if you really need vec() equivalent, how
about Robert Feldt’s BitVector?

See http://www.ruby-lang.org/en/raa-list.rhtml?name=BitVector.

Ahh, I will try your suggestion and look into the BitVector extension as
well, thank you!
