nx_ip_status_check() blocks forever even if timeout is specified

Question

nx_ip_status_check() blocks forever even if timeout is specified

Licio MAPELLI 51

The nx_ip_status_check(, , NX_IP_INITIALIZE_DONE | NX_IP_LINK_ENABLED | NX_IP_INTERFACE_LINK_ENABLED, timeout) internally calls tx_mutex_get(&(ip_ptr -> nx_ip_protection), TX_WAIT_FOREVER); that blocks forever in case the requested conditions are not meet.

Shouldn't be tx_mutex_get(&(ip_ptr -> nx_ip_protection), timeout) ?

Thanks

I don't think this is a bug in nx_ip_status_check. It should be fixed in the network driver.

Thanks for your suggestion, however the nx_ip_status_check() could become blocking, regardless of the timeout passed in the arguments, depending by the subtending driver behavior (buggy or not). I believe this possible deviation from the expected API behavior should be fixed to make it consistent with the documentation and predictable. Thanks
