[lwip-users] OS-less Active Web Server with RAW API.

[Welson Sun]

Hi,
 
I am trying to use lwip's raw API to implement an active webserver on a
Xilinx Virtex II Pro chip (which has PowerPC embedded). The webserver serves
as a GUI and the user can select test items with a web browser. After the
webserver gets the test request, it parses the URL and do the requested
tests and sends the test result back as webpages.
 
My current question is: without an OS, the whole program is a single
process. If the test takes some time, how can I call the tcp_fasttmr() and
tcp_slowtmr() according to the requirements?
