Should std::unique_ptr be permitted

Question

This is a very simple question. Consider the following code:

#include 
#include 

typedef std::unique_ptr UniqueVo         


        

Answer 1

Don't delete variables of void *。

If you want to work with something like Win32 Handles, please provide a custom deleter.

For example:

void HandleDeleter(HANDLE h)
{
    if (h) CloseHandle(h);
}

using UniHandle = unique_ptr>;

Then:

UniHandle ptr(..., HandleDeleter);
