Even if you fixed the initialized data problem, this code is still a bug waiting to happen. It should be a single bool in the struct to handle the state for the function as there are only two states that actually make sense.

succeeded = true; error = true; //This makes no sense

succeeded = false; error = false; //This makes no sense

Otherwise if I'm checking a response, I am generally going to check just "succeeded" or "error" and miss one of the two above states that "shouldn't happen", or if I check both it's both a lot of awkward extra code and I'm left with trying to output an error for a state that again makes no sense.
