44.1. slapi_vattr_list_attrs()
Description
This function returns all the attribute types, both real and virtual, from an entry. You can call slapi_vattr_values_type_thang_get() and take the values present in the vattr_type_thang list rather than calling slapi_vattr_values_get() to retrieve the value.
This function should be used to return both the real and virtual attributes for an entry.
