Question:
Does anyone know the standard work around for segment span using
_huge* pointers and GlobalAlloc? If we can't use over a 64K
chunk of memory at one time...why do we even bother? Every other
OS in the WORLD can do it...there must be a patch somewhere.
Answer:
Using huge pointers allows you to create and access blocks of
data> 64K. The only caveat is that a single data element may
not cross a 64K border. So, if your block of memory contains an
array of structures, make sure that the structure has a sizeof()
which is a power of 2.
