Static Variables

[amateurrobotguy]

If I want to define a variable inside of a function and want it to be available to all functions in the .c file, will static do it?

Would this work?

void FunctitonWhatever1(void)
{
static int bob=1;
/*Note the static and the =1*/
CallerFuction();
}

void CallerFunction(void)
{
int bill=0;
/*Only need it in this function*/
bill=2+bob;
}
