Awesome hacky code!

gistfile1.cpp

// I've left parameters as-is, but success / failure might be constants?
// (if so, hash define them)
// also, I would usually pass in the records directly, rather than using
// global variables:
//    Record *records,
//    size_t n_records,
//
void list_generator(
    int (*process)(Record, string[]),
    string options[],
    string success,
    string failure
) {
    size_t n_matched = 0;
    // what's up with your <= ?
    // is recordcount not actually a count, but actually the last index?
    for (int i = 0; i <= recordcount; i++) {
        Record r = records[i];
        if ((*process)(r, options) > 0) {
            // if this is the first matched record,
            // print the success string
            if (!n_matched)
                cout << success;
            n_matched++;

            // then print the record title
            cout << r.title << endl;
        }
    }
    // if no records were matched,
    // print the failure string
    if (!n_matched)
        cout << failure;
