BosFn(bool (*fn)(bool))

A constructor for a function that pops itself off the BrainOS function list if it returns true.

Parameters

• fn - The function to be called

Explanation

Functions in C++ are sort of weird. They are (sort of) just pointers to a block of memory that contains the code for the function. Because of this, you can pass functions as parameters to other functions. The actual syntax for this is a bit weird, but it is very useful. The syntax is bool (*fn)(bool). This means that the function takes a boolean parameter, and returns a boolean. The * means that the function is a pointer, and the () means that the function is a parameter. The bool before the * means that the function returns a boolean. The bool after the () means that the function takes a boolean parameter.

Example

void myBosFn(bool remake){
    //drawing code here
}
int main(){
    BosFn::addNewFn(BosFn(myBosFn));
}
