检查C中指向void *的指针类型

Question

In my C program I am using void* pointers. Is there anyway to check in an if statement if the void* pointer is pointing to an int* or a char*?

Answer 1

Nope. There is no run-time type information in C. A void* is just an address. That's it. It's completely up to the programmer to know / keep track of what information a void* points to.

With more information about how/why you're using void* , a workaround could possibly be suggested.
