These functions provide convenience APIs for accessing specific properties of the relevant resource type, resource, and resource group, including some commonly used extension properties. The DSDL provides the scds_initialize() function to parse the command-line arguments. The library caches the various properties of the relevant resource type, resource, and resource group.
The scds_property_functions(3HA) man page describes these functions, which include the following:
scds_get_ext_property-name
scds_get_rg_property-name
scds_get_rs_property-name
scds_get_rt_property-name
