Callback c++ c

//Define a type for the callback signature,
//it is not necessary, but makes life easier

//Function pointer called CallbackType that takes a float
//and returns an int
typedef int (*CallbackType)(float);  


void DoWork(CallbackType callback)
{
  float variable = 0.0f;

  //Do calculations

  //Call the callback with the variable, and retrieve the
  //result
  int result = callback(variable);

  //Do something with the result
}

int SomeCallback(float variable)
{
  int result;

  //Interpret variable

  return result;
}

int main(int argc, char ** argv)
{
  //Pass in SomeCallback to the DoWork
  DoWork(&SomeCallback);
}
