Use dce_attr_sch_bind to acquire the handle. dce_attr_component_name_t A pointer to a character string used to further specify a schema object. dce_bind_auth_info_t A enumeration that defines whether or not the binding is authenticated. This data type is defined exactly as the sec_attr_bind_auth_info_t data type in the ERA interface. See the sec_intro(3sec) reference page for more information on sec_attr_bind_auth_info_t. dce_attr_schema_entry_t A structure that defines a complete attribute entry for the schema catalog. This data type is defined exactly as the sec_attr_schema_entry_t data type in the ERA interface. See the sec_intro(3sec) reference page for more information on sec_attr_schema_entry_t. dce_attr_cursor_t A structure that provides a pointer into a database and is used for multiple database operations. This cursor must minimally represent the object indicated by dce_attr_sch_handle_t. The cursor may additionally represent an entry within that schema. dce_attr_schema_entry_parts_t A 32-bit bitset containing flags that specify the schema entry fields that can be modified on a schema entry update operation. This data type is defined exactly as the sec_attr_schema_entry_parts_t data type in the ERA interface. See the sec_intro(3sec) reference page for more information on sec_attr_schema_entry_parts_t. ##
