什么是“typedef void FuncType（double，int）”？

Question

我不明白typedef void (*p)(double, int)的含义！ 但我不明白typedef void FuncType(double, int)的含义！

示例：

void test(double, int) {}
typedef void FuncType(double, int);
//using FuncType = void(double, int);

int main() {
    FuncType *f = test;
    f(1, 3);
    FuncType ft;
    ft(10, 50);//ERROR: 'unresolved external symbol' during compilation process
    return 0;
}
