Description
Adds an attribute with the specified key and value to the device.
To define the display name of your device in the RAD Studio IDE, add an attribute to your device with sDevAttrDisplayName as key and the desired display name as value.
If an attribute with the specified key already exists, AddAttribute raises an EInvalidOpException exception with the following message:
- Attribute '<key>' already exists
Use HasAttribute to check whether or not an attribute with a given key already exists.
