Detailed Description

Searches for all global chunks by pattern matching against the names of (Kernel side) chunk objects.

The match pattern can be set into this object at construction; it can also be changed at any time after construction by using TFindHandleBase::Find().

After construction, call TFindChunk::Next() repeatedly to find successive chunks whose names match the current pattern. A successful call to TFindChunk::Next() means that a matching chunk has been found.
