3.3 Find all the Variables in a Group: NF_INQ_VARIDS

Find all varids for a location.

Usage

     INTEGER FUNCTION NF_INQ_VARIDS(INTEGER NCID, INTEGERS VARIDS)
NCID
The group id for this operation.
VARIDS
An already allocated array to store the list of varids. Use nf_inq_nvars to find out how many variables there are. (see NF_INQ Family).

Errors

NF_NOERR
No error.
NF_EBADID
Bad group id.
NF_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 NF_OPEN).
NF_ESTRICTNC3
This file was created with the strict netcdf-3 flag, therefore netcdf-4 operations are not allowed. (see NF_OPEN).
NF_EHDFERR
An error was reported by the HDF5 layer.

Example

This example is from nf_test/ftst_groups.F.

     C     Check varids in subgroup.
           retval = nf_inq_varids(subgrp_in, nvars, varids_in)
           if (retval .ne. nf_noerr) call handle_err(retval)
