Get subpart of data from key

Documentation

Get subpart of data from key. Note, this usually implies the data is rather large so some form of a "sparse virtual memory emulation" will be used to "page-in" segments of the imported data.
Returns:
data buffer of subsection. It is the user's responsibility to deallocate the memory when done.
Parameters:
startIndex - beginning of subsection to extract.
endIndex - end of subsection to extract. If endIndex is NULL it means extract to the end. endIndex must be either NULL or greater than or equal to startIndex.
sze - passed as pointer. Returns sze of data extracted. If key has no data yet returns 0.
