uOptional flag that the key and value are Unicode (UTF16)
filenameDatabase opened with @UNQOPEN
keyKey to add or replace
bhandleBinary handle returned by @BALLOC
lengthOptional length (in bytes) to write (if -1 or nor specified, write the entire buffer)

This example opens a database named "test.db", then allocates a binary buffer, writes it to the database, and then reads it back.


echo %@unqopen[rwc,test.db]

set handle=%@balloc[4096]

echo %@unqkvb[test.db,"bbb",%handle,-1]

echo %@unqreadb[test.db,"bbb",%handle,-1]

echo %@unqclose[test.db]
