unique_ptr and make_unique -- [SOLVED]

[Richard Andrew x64]

[See below the original question for the solution.] I have been struggling with this for a while now, and I can't seem to figure it out. Here's my declaration:

std::unique\_ptr\>		\_VersionData{};

And here's where I attempt to instantiate it:

\_VersionData = std::make\_unique(new BYTE\[\_VersionDataLength\], \[\](BYTE\*\* ptr) {delete \*ptr; }); // Attempting to use a lambda expression as a custom destructor

The errors I receive are:

error C2440: 'initializing': cannot convert from 'initializer list' to 'unsigned char *'
note: The initializer contains too many elements

I'm probably way off in my interpretation of the documentation. Can someone show me how this is supposed to work? :) [SOLUTION] Turns out I was really way off with the attempt shown above. Here's the working code. The declaration in the class header file:

std::unique\_ptr					\_VersionData;

The instantiation in the source file:

auto CustomDeleter = \[\](BYTE\* ptr) {delete\[\] ptr; };

\_VersionData = std::unique\_ptr(new BYTE\[\_VersionDataLength\], CustomDeleter);

And the most important part, the constructor initializer list:

CFileVersionInfo::CFileVersionInfo()
: _VersionData(nullptr, [](BYTE* ptr) {delete[] ptr; })
{
// constructor code here...
}

The difficult we do right away... ...the impossible takes slightly longer.

Now that you understand it, how about writing an article for the rest of us?

Thanks for the vote of confidence, Richard! :-D I can't say that I completely understand it. Getting it to work was partly just trying different things until I hit upon the magic combination! I do understand some parts of it better now, but hardly well enough to write an article. :)
