void* 形参如何传递参数

typedef struct {
    int age;
    bool gender;
    string name;
} member ;


bool getMember(void **pVoid) {
    member NewMember;
    NewMember.age = 18;
    NewMember.gender = true;
    NewMember.name = "Hero";

    *pVoid = &Nie;

    return true;
}

bool getMember2(void **pVoid) {
    member **pBuffer = reinterpret_cast<member **>(pVoid);

    member NewMember;
    NewMember.age = 18;
    NewMember.gender = true;
    NewMember.name = "Hero";

    *pBuffer = &NewMember;

    return true;
}

int main() {

    void *pReturn;

    void *Me;
    getMember(&Me);
    member *pMember = reinterpret_cast<member *>(Me);
    printf("age of mine is %d\n", pMember->age);

    member *Me2;
    getMember2((void **)&Me2);

    if (Me2 != nullptr) {
        printf("age of Me2 is %d\n", Me2->age);
    } else {
        printf("Me2 is Null!");
    }

    return 0;
}
