Function Pointer for Compatibility?

lib.c

#include "lib.h"

int give_me_callback(Callback callback) {
    return callback(1, 2.2, "3");
}

lib.h

typedef int Callback(int, double, const char *);

int give_me_callback(Callback callback);

main.c

#include "lib.h"

// Defines a callback but incompatible with lib's callback type.
int callback_4args(int a, double b, const char *c, void *d)
{
    return a;
}

int main() {
    return give_me_callback(callback_4args); // Warning, but compiles and runs.
}
