3.4 Find all Dimensions Visible in a Group: nc_inq_dimids
Find all dimids for a location. This finds all dimensions in a group,
or any of its parents.
Usage
int nc_inq_dimids(int ncid, int *ndims, int *dimids, int include_parents);
ncid- The group id for this operation.
dimids- An already allocated array of ints when the dimids of the visible
dimensions will be stashed. Use nc_inq_ndims to find out how many dims
are visible from this group. (see nc_inq Family).
include_parents- If non-zero then all the dimensions in all parent groups will also be
retrieved.
Errors
NC_NOERR- No error.
NC_EBADID- Bad group id.
NC_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 nc_open).
NC_ESTRICTNC3- This file was created with the strict netcdf-3 flag, therefore
netcdf-4 operations are not allowed. (see nc_open).
NC_EHDFERR- An error was reported by the HDF5 layer.
Example
This example is from libsrc4/tst_dims.c.
int ncid, dimid;
int ndims_in, dimids_in[MAX_DIMS];
...
/* Open the file and make sure nc_inq_dimids yeilds correct
* result. */
if (nc_open(FILE_NAME, NC_NOWRITE, &ncid)) ERR;
if (nc_inq_dimids(ncid, &ndims_in, dimids_in, 0)) ERR;
if (ndims_in != 1 || dimids_in[0] != 0) ERR;
