// Create a custom function with a handler function:
Var f As New SQLiteFunctionMBS
f.name = "SHA256"
f.ArgumentCount = 1
f.Flags = f.kFlagDeterministic OR f.kFlagUTF8 OR f.kFlagInnocuous
// Text encoding UTF8, function is deterministic and can be cached, function is innocuous as it depends only on parameters
AddHandler f.Perform, AddressOf PerformSHA256
functions.Append f // keep reference
