Generate and return the action
attribute of the input file
or unit
.
The action
attribute of a connected file
or unit
is returned by the Fortran intrinsic inquire()
statement.
Possible values are, "READ"
, "WRITE"
, "READWRITE"
. If there is no connection, the value returned is "UNDEFINED"
.
- Parameters
-
[in] | unit | : The input scalar, or array of arbitrary rank, of type integer of default kind IK representing the file unit whose action attribute is to be returned.
(optional, it must be present if and only if the input argument file is missing.) |
[in] | file | : The input scalar, or array of arbitrary rank, of type character of default kind SK representing the file path whose action attribute is to be returned.
(optional, it must be present if and only if the input argument unit is missing.) |
- Returns
action
: The output scalar, or array of same rank, shape, and size as the input array-like argument, of type character
of default kind SK of length type parameter 9
, containing the action
attribute of the input file
or unit
.
If the length of the output value is less than 9
, it is left-adjusted and padded with blanks.
