Berkeley DB: db_env_set_panicstate
db_env_set_panicstate
|
 
|
#include <db.h>
int
db_env_set_panicstate(int panic);
Description
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.
Errors
The db_env_set_panicstate function may fail and return a non-zero error for the following conditions:
- EINVAL
- An invalid flag value or parameter was specified.
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.
