int db_env_set_panicstate(int panic);
Toggle the Berkeley DB panic state. Setting panic to a non-zero value causes Berkeley DB to refuse attempts to call Berkeley DB functions with the DB_RUNRECOVERY error return.
The db_env_set_panicstate interface affects the entire application, not a single database or database environment.
The db_env_set_pageyield interface may be used to configure Berkeley DB at any time during the life of the application.
The db_env_set_panicstate function returns a non-zero error value on failure and 0 on success.
The db_env_set_panicstate function may fail and return a non-zero error for the following conditions:
The db_env_set_panicstate function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions. If a catastrophic error has occurred, the db_env_set_panicstate function may fail and return DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
