In the lwip port to rtxc, i find that the timeouts is processed only =
when an application task issues a blocking call, such as sys_sem_wait. I =
begin to think now, If a design uses a single task, which has scheduled =
some timeouts and which has no potential blocking calls, then How and =
where will the timeouts be serviced ? Can someone explain this concept ?
In the 6502 port, there is no OS and the stack runs as if it is a single =
thread of execution. In this case, as expected, the timeouts are =
serviced in the sys_main.=20
Thanks,
