I have a function that accepts a function pointer like so:
void invoke(void (*fnCallback)(int data)) { ... }
I also have a class method from which I would like to call this function, and pass the callback as a lambda:
void Class::testInvoke() {
auto f = [](int data) -> void { data = data + 1; };
invoke(f);
}
This works, but if I try capturing with the lambda, the code does not compile:
void Class::testInvoke() {
int value = 1;
auto f = [=](int data) -> void { data = data + value; };
invoke(f);
}
In the second case, if I comment out the invoke(f) line, the code compiles. What am I doing wrong? How do I need to change the signature of invoke so it accepts captured lambdas?
