Re: [bug-gawk] Adding an API hook to enable a select extension

[Aharon Robbins]

Hi Andy.

If you add to the API, please name the function lookup_file and not
file_lookup.

The linear search through the redirection list is not likely to be
a bottle neck that we would need a hash table. Actual I/O swamps
that kind of thing, for sure.

I suggest that we start a new branch for experimenting with this
stuff instead of dropping something directly into master.

The first step is to extend the API. The second step is to implement
a select function and write some code to use it.

Then "lather, rinse, repeat" until everyone is happy.

I don't have answers to the questions about dispatching mechanisms. There
is the (originally) System V poll() interface but I don't think we
should go there - select is likely to be the most available.

Thanks,

Arnold
