NDF_ISACC
- Determine whether a specified type of NDF access is available
- Description:
The routine determines whether a specified type of access to an
NDF is available, or whether it has been disabled. If access is
not available, then any attempt to access the NDF in this way
will fail.
- Invocation:
CALL NDF_ISACC( INDF, ACCESS, ISACC, STATUS )
- Arguments:
-
INDF = INTEGER (Given)
-
NDF identifier.
-
ACCESS = CHARACTER * ( * ) (Given)
-
The type of NDF access required: 'BOUNDS', 'DELETE', 'SHIFT',
'TYPE' or 'WRITE' (see the Notes section for details).
-
ISACC = LOGICAL (Returned)
-
Whether the specified type of access is available.
-
STATUS = INTEGER (Given and Returned)
-
The global status.
- Notes:
The valid access types control the following operations on the
NDF:
-
'BOUNDS' permits the pixel-index bounds of a base NDF to be
altered.
-
'DELETE' permits deletion of the NDF.
-
'SHIFT' permits pixel-index shifts to be applied to a base
NDF.
-
'TYPE' permits the data types of an NDF's components to be
altered.
-
'WRITE' permits new values to be written to the NDF, and the
state of any of its components to be reset.
