Hello, Camlers!

I have the following problem when = using Unix=20 module:

I issuing 'connect' for = nonblocked-mode=20 socket.

This can raise EINPROGRESS error = meaning=20 connect is not yet complete.

Then (as I taught by manuals) I = use 'select'=20 method and then 'getsockopt_int sock SO_ERROR' to retreive connect=20 results.

The problem is: 'getsockopt_int' = returns=20 'int' while I need Unix.error type.

I can't map int to error in good=20 way.

Of couse, I can use some = workarounds (and I=20 had to use one), but they all are not look good.

May be is it the time to = extend Unix=20 module API?

For example, add function like=20 'getsockopt_error' or 'int_to_error'?

Seva
