For connect, I wrote a unit that implements a connect timeout, see:

I thought MSG_DONTWAIT is actually the flag to switch to nonblocking mode,
isn't it? As a matter of fact, the fprecv() above would get a result of -1
and a sockterror of "Try Again", which is exactly the behavior of
nonblocking read.

Will this be a CPU hog:
t := Now;
while fprecv(s, @buf, buf_len, MSG_DONTWAIT) < 0 do begin
if Now - t > 0.1 * timeout then Break; // approx. seconds
end;
Thanks

I seem to remember that synapse can do this.
Otherwise for non-standard protocols use fpconnect(), fpselect() etc.
