What`s the meaning of the MSG_GET

[vingo]

Hi
Here`s question that
In the Twain19.pdf the MSG_GET is described as follow:
MSG_GET : Return a Capability’s valid value(s) including current and default values

Is that mean MSG_GET will get two value(the default one and the current one)?

Is someone can explain it for me ? THX

The retrieved values depend on the capability that you’re querying and the container that you’re using to retrieve the values.

If you use a container that can contain only one value you’ll retrieve exactly one value.
