I understand this mainly from hearsay, and personal experience. In Greg
Winton, Palm OS Network Programming, O'Reilly, p199, it says "On Windows
and Max machines, the host's sockets API do not support timeouts, so this
parameter is ignored." It then goes on to say that POSE appears frozen
until the call "times out." I asked at PalmSource and nobody seemed to know
too much about it, except that there used to be a bug that had been fixed.
In my code, I set the timeout to 20 seconds which appears to be the case on
a real device (I haven't actually set up a scenario that will take forever
and timed the timeout). With POSE the same code often times out on the host
stack in what I estimate to be 2 seconds (definitely way less than 20
seconds), but doesn't seem to do the same using the NetLib stack. I guess
have never seen it written that there is a two second timeout... and I also
haven't spent that much time investigating since it didn't seem to be a big
obstacle.
If you have any ideas as to how I can figure out if I'm doing something
wrong I'd be pleased to hear it. (I have just upgraded to POSE 3.4)
Code snippets...
#define genNetLibTimeout (sysTicksPerSecond * 20)
:
AppNetTimeout = genNetLibTimeout;
:
bytes = read(context->socketRef, c, sizeof(Char));
