Remarks
ReAllocCoTaskMem is one of two memory reallocation methods in the Marshal class. (ReAllocHGlobal is the other.) The beginning of the reallocated memory content is the same as the original content; however, the entire memory block can be in a different location. This method exposes the COM CoTaskMemRealloc function, which is referred to as the COM task memory allocator.
