- * This function uses a hook (`mbedtls_test_err_add_hook`) to allow invasive
- * testing of its inputs. This is used in the test infrastructure to report
- * on errors when combining two error codes of the same level (e.g: two high
- * or two low level errors).
- *
- * To set a hook use
- * ```
- * mbedtls_set_err_add_hook(&mbedtls_check_foo);
