3.1 Find a Group ID: NF_INQ_NCID
Given an ncid and group name (NULL or "" gets root group), return
ncid of the named group.
Usage
INTEGER FUNCTION NF_INQ_NCID(INTEGER NCID, CHARACTER*(*) NAME, INTEGER GRPID)
NCID- The group id for this operation.
NAME- A character array that holds the name of the desired group. Must be
less then NF_MAX_NAME.
GRPID- The ID of the group will go here.
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 getting the group by name
retval = nf_inq_ncid(ncid, group_name, grpid_in)
if (retval .ne. nf_noerr) call handle_err(retval)
