GETDVI(device-name,item)

device-name

specifies a physical device name or a logical name equated to a physical device name. Specify the device name as a character-string expression.

After the device-name argument is evaluated, the F$GETDVI lexical function examines the first character of the name. If the first character is an underscore (_), the name is considered a physical device name. Otherwise, a single level of logical name translation is performed, and the equivalence name, if any, is used.

is a character variable that contains any item accepted by the F$GETDVI lexical function (for example, the physical device name). For more information about the F$GETDVI lexical function, see OpenVMS DCL Dictionary.

The GETDVI function returns the device information as a character string. If the device information string is longer than the length of the target variable, it is truncated.
