RE: [lwip-users] critical section protection + timer issues

[Tom C. Barker]

Scott,

 

I hope this helps at least part of what you are dealing with. I have one and only

one thread that runs the stack, timers, etc. In order to get myself into the stack

so as to have the stack "establish a TCP connection on behalf of an

arbitrary thread" I call tcpip_callback(void (*f)(void *ctx), void *ctx) in

tcpip.c. The callback then gives me, under the lwIP thread, execution time for

arbitrary _code_ which wants to establish a tcp connection. (tcpip_callback can

be done from any thread since it is interacting with your thread-safe message box.)

 

As long as all sockets are initialized in the lwip thread directly or are executed via

a callback to the lwip thread, your tcp timer will always run under the one lwIP thread.
