3.8 Find a Group's Parent: NF90_INQ_GRP_PARENT

Given ncid, find the ncid of the parent group.

When used with the root group, this function returns the NF90_ENOGRP error (since the root group has no parent.)

Usage

       function nf90_inq_grp_parent(ncid, parent_ncid)
         integer, intent(in) :: ncid
         integer, intent(out) :: parent_ncid
         integer :: nf90_inq_grp_parent
NCID
The group id.
PARENT_NCID
The ncid of the parent group will be copied here.

Errors

NF90_NOERR
No error.
NF90_EBADID
Bad group id.
NF90_ENOGRP
No parent group found (i.e. this is the root group).
NF90_ENOTNC4
Attempting a netCDF-4 operation on a netCDF-3 file. NetCDF-4 operations can only be performed on files defined with a create mode which includes flag HDF5. (see NF90_OPEN).
NF90_ESTRICTNC3
This file was created with the strict netcdf-3 flag, therefore netcdf-4 operations are not allowed. (see NF90_OPEN).
NF90_EHDFERR
An error was reported by the HDF5 layer.
