help needed for while loop!!!

[sergelaurent]

I have the following code

while(1) {
if(toto==1) {
....
} elseif(toto==2) {
...
}
}

toto is a globlal variable.
I have noticed that if I initialise toto to 0 at the start of my program and when I set it to 1 later, the change in the value of toto is not refreshed in my while loop.
So, I wanted to know how to refresh the value of toto continuously or every periood time in my while loop?

It's impossible behaviour (with undefined notion of value refreshing). But in this case (as in a snippet above) you never set toto to 1 because of there are only toto==1 and toto==2 (skipped) branches in the loop with initial value of toto==0. So you have and idle loop forever...
What is it refresh the value in your case? Have you any refreshing thread or what else?

The short answer is find a better way of solving the problem.

The quick answer is to say

volatile int toto = 0;

Then, whenever you modify the variable 'from outside', then loop will immediately pick up the change.
