result = mg_nc_decompose(file_id, descriptor [, parent_type=long] [, parent_id=long], group_id=group_id [, element_name=string] [, /write] [, error=long])

Determines the type of element described by descriptor, i.e., invalid (0), attribute (1), variable (2), or group (3).

Note: this routine will create required groups if WRITE is set.

element type code as a long

file_id in required type=long

netCDF file identifier, should be open for writing if WRITE is set

descriptor in required type=string

string description of attribute, variable, or group

parent_type out optional type=long: element type code for parent element, can only 2 or 3
parent_id out optional type=long: netCDF identifier for parent element
