-
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$GETDVI lexical
function examines the first character of the name. If the first character
is an underscore (_), the name is considered a physical device name. Otherwise,
a maximum of 10 levels of logical name translations are performed, and the
equivalence names, if any, are used.
-
item
-
is a character variable that contains
any item accepted by the F$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.
