我应该如何键入cast void *？

Question

I am learning C. I need to define a function to type cast the value of void * to the desired type. I'm not sure if I fully understand what I need to do. Here is my attempt. Can someone take a look and let me know if it's correct? If not, how should I fix it? Thank you in advance for your time.

void print_type(TYPE a)
{
    void *v_ptr;
    v_ptr = &a;

}

In C, void * is implicitly compatible with any data pointer type. If you have a POSIX implementation, then it's compatible with function pointers as well. There's no need for typecasting; conversely, it's even considered harmful .
