Additional information

General information:

size: always means "bytes"
length: always means "elements"

example: the size of UINT64 [2] is 2*8 = 16, the length of UINT64 [2] is 2

All interfaces you get have an initial reference count of 1. To increment the count call 'AddRef' and to decrement it call 'Release'. When the count reaches 0, the interface will be destroyed.
Every interface you don't need anymore should be released.
