No the staf service request returns immediately with the socket error
(see previous posts). I realize there are no actual socket/tcp
options for read timeouts; however within the socket implementation
you have provided you have implemented a timeout when performing a
read that returns the error code 22.
The particulars of the requests I am issuing should never take long;
ie I don't need to implement any waits; I'm simply resolving a
variable or performing a non-recursive file listing.
It sounds as if the timeout on a recv() is what I'm looking for.
Thanks for your help Sharon, much appreciated.
