3.2 Get a List of Groups in a Group: NF_INQ_GRPS
Given a location id, return the number of groups it contains, and an
array of their ncids.
Usage
INTEGER FUNCTION NF_INQ_GRPS(INTEGER NCID, INTEGER NUMGRPS, INTEGER NCIDS)
NCID- The group id for this operation.
NUMGRPS- An integer which will get number of groups in this group.
NCIDS- An array of ints which will receive the IDs of all the groups in this
group.
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 What groups are there from the root group?
retval = nf_inq_grps(ncid, ngroups_in, grpids)
if (retval .ne. nf_noerr) call handle_err(retval)
