# NCDF_DIMIDSINQ

The NCDF_DIMIDSINQ function returns an array of dimension IDs for all dimensions in a given group (and optionally for the group’s parents).

## Examples

See the example for NCDF_GROUPNAME.

## Syntax

Result = NCDF_DIMIDSINQ( Grpid [, /INCLUDE_PARENTS] )

## Return Value

Returns an array of all dimension IDs associated with the specified group. If no dimension IDs exist, or if the file is not a NetCDF 4 file (or a NetCDF 3 file without groups), the scalar value -1 is returned.

## Arguments

### Grpid

The ID of the group to query, returned from a previous call to NCDF_OPEN, NCDF_CREATE, or NCDF_GROUPDEF.

## Keywords

### INCLUDE_PARENTS

Set this keyword to also return the IDs of the dimensions associated with the group’s parents.
