CDatabase::useCursorLib vs. CRecordset::snapshot

[9271022]

MFC CDatabase::OpenEx() allows an option useCursorLib.
According to MSDN documentation, specify the option for
snapshot support. While in CRecordSet::Open(), the first
parameter is record set type. What is relationship
between useCursorLib and snapshot? What will happen if
useCursorLib is not specified but snapshot record set is
requested?

My question is summarized as follows.

CDatabase CRecordset resultant data set

useCursorLib snapshot snapshot?
useCursorLib dynaset snapshot?
Not useCursorLib snapshot snapshot?
Not useCursorLib dynaset dynaset?

Thank you in advance.
