[q] socket and timeout

Hello,

I should make a request and get response from a Socket constrained by
timeout. I.e.:

myTimeout := 5. "seconds"
[
...
socket sendByteArray: request.
response := socket receiveByteArray: responseSize.
...
] on: TimeoutError do: [ :e | self handleError: e ].

How can I achieve something similar?

Another question:

Does anybody try to set SO_SNDTIMEO and SO_RCVTIMEO options with setsockopt
WinSock function? And will it work in Dolphin Smalltalk?

Hi Dmitry,

AFAIK, For Winsock1.1, there is no way to change the timeout values from the
OS defaults (which I believe are around a couple of minutes).

Yes, I did implement these options in Dolphin's Socket class, but they didnt
seem to have any effect. It appears that Dolphin would need to use the
Winsock2 library directly for these options to be available.

The approach I take in my HTTPClient is to fork a timeout process.
