Function running confuse on VxWorks -

we're trying use vxworks' udp multicast.
using command line (->), call initialization function parameters , multicast runs successfully.

when try run method code, initialization function returns ok (no errors), not initialize multicast udp port.

is there catch ?

one thing aware of tcp/ip stack gets initialized after roottask completes.

the usrappinit function runs in context of root task. if invoking network stack elements in usrappinit, things might not work.

make sure invoke networking code task has been spawned lower priority network stack (which runs @ priority 50).
