TR24731-1 provides a consistent mechanism to handle constraints violations that are discerned at runtime. Most functions defined by TR24731-1 include as part of their specification a list of runtime-constraints. Library implementations must verify that the runtime-constraints for a function are not violated by the program. If a runtime-constraint is violated, the currently registered runtime-constraint handler is called.
