Assunto: RE: How to allocate more than 64KB?
But I've call MemHeapFreeBytes() to get the largest chunk, it's also larger
than 1M.
Can I allocate in this chunk?

If you have only 1.9M there are some chances that you cannot allocate 1M
because you may not have a contiguous memory segment which fit in 1M.

That's 2Mb. Did you check the free heap space before?
