Remarks
AllocCoTaskMem is one of two memory allocation API methods in the Marshal class. (Marshal.AllocHGlobal is the other.) The initial memory content returned is undefined, and the allocated memory can be larger than the requested number of bytes. This method exposes the COM CoTaskMemAlloc function, which is referred to as the COM task memory allocator.
