I'd need a class like std::auto_ptr for an array of unsigned char*, allocated with new[]. But auto_ptr only calls delete and not delete[], so i can't use it.

I also need to have a function which creates and returns the array. I came out with my own implementation within a class ArrayDeleter, which i use like in this example:

#include <Utils/ArrayDeleter.hxx>

typedef Utils::ArrayDeleter<unsigned char> Bytes;

void f()
{
  // Create array with new
  unsigned char* xBytes = new unsigned char[10];
  // pass array to constructor of ArrayDeleter and
  // wrap it into auto_ptr
  return std::auto_ptr<Bytes>(new Bytes(xBytes));
}

...
// usage of return value
{
  auto_ptr<Bytes> xBytes(f());
}// unsigned char* is destroyed with delete[] in destructor of ArrayDeleter

Is there a more elegant way to solve this? (Even using another "popular" library)
