C ++超时功能

Question

I want to realize a timeout function in C++ on a Atmel evaluation kit.

The program should open the function "start()" and if this function is not completed within "0.5s" it should be killed.

Are there any existing function to do jobs like this?

Answer 1

Yes: std::future::wait_for . You get either future_status::ready or future_status::timeout .

Answer 2

In my experience, these kinds of functions are always hand-crafted because in embedded systems, the target system is not standardized.

You could purchase an OS and use methods like messaging timeouts and sleeping.

Without an OS, you have to craft the functionality yourself using a timer and the timer interrupt (ISR).
