# These tests complement those in capi2.test. They are organized
# as follows:
#
# capi3c-1.*: Test sqlite3_prepare_v2 
# capi3c-2.*: Test sqlite3_prepare16_v2 
# capi3c-3.*: Test sqlite3_open
# capi3c-4.*: Test sqlite3_open16
# capi3c-5.*: Test the various sqlite3_result_* APIs
# capi3c-6.*: Test that sqlite3_close fails if there are outstanding VMs.
