Auto pointer for unsigned char array?
c++
Solution
Boost has a variety of auto-pointers, including ones for arrays. Have you considered if std::vector is sufficient? Vectors are guaranteed to be contiguous in memory, and if you know the size and allocate memory ahead of time via `reserve()` or `resize()`, the location in memory will not change.
Problem
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)
