This is probably a silly question, but I can't seem to find the answer on Google or MSDN.

Here is my question:

Do I have to delete the pointer to the string given to me by ID3DXBaseEffect::GetString, or is it deleted when I release the effect?

i.e.

ID3DXEffect *pEffect = ...; // would be pointing to the loaded effect

D3DXHANDLE strHandle = ...;  // would be pointing to the string parameter

LPCSTR strValue;


if (FAILED(pEffect->GetString(strHandle, &strValue)))

{

     // handle the error

}


// do something with 'strValue'


delete strValue;  // do I need this???

Most likely it returns a pointer into an internal structure someplace that is managed by D3DX. I doubt you need to delete it yourself.

The corollary to that: if you want to modify the string, you of course shouldn't do it through the pointer returned (the pointer is const so you can't do this without a cast, anyway), but rather duplicate the string into your own buffer first.

That's what I was suspecting, but I figured that I would rather be safe than sorry :happy: .
