Previous: NDF_TYPE - Obtain the numeric type of an NDF array component
- Description:
The routine unmaps an NDF, or a individual NDF array which has
previously been mapped for READ, UPDATE or WRITE access.
- Invocation:
CALL NDF_UNMAP( INDF, COMP, STATUS )
- Arguments:
-
INDF = INTEGER (Given)
-
NDF identifier.
-
COMP = CHARACTER * ( * ) (Given)
-
Name of the NDF component to be unmapped: 'AXIS', 'DATA',
'QUALITY', 'VARIANCE' or '*'. The last value acts as a wild
card, causing all mapped arrays to be unmapped.
-
STATUS = INTEGER (Given and Returned)
-
The global status.
- Notes:
-
This routine attempts to execute even if STATUS is set on
entry, although no further error report will be made if it
subsequently fails under these circumstances.
-
A component name of 'AXIS' will act as a partial wild card,
unmapping any axis arrays which are mapped, but leaving other
components unchanged. The routine NDF_AUNMP may be used to unmap
individual axis arrays.
-
A comma-separated list of component names may also be given, in
which case each component will be unmapped in turn.
-
An error will be reported if a component has not previously
been mapped for access, except in the case where a value of '*'
is given for COMP, or where 'AXIS' is used to unmap axis arrays.
