Compiler: [CC3220S/SDK4.10] Is there a good way to break select() function when timeout is NULL?

Tool/software: TI C/C++ Compiler

Hi Ti,

For LPDS feature on CC3220S, we apply timeout with NULL at select function.

My question is How to break from select function?

On PC linux env, we can use signal and pipe to break select function, how about CC3220S?

Thanks.
