# Description

Applications installing application-specific recovery methods need to be called before Berkeley DB performs recovery so they may add their recovery methods to Berkeley DB's.

The DbEnv.set_recovery_init method supports this functionality. The db_recovery_init_fcn method must be declared with one argument, a reference to the enclosing Berkeley DB environment. This method will be called after the DbEnv.open has been called, but before recovery is started.

If the db_recovery_init_fcn method returns a non-zero value, no recovery will be performed and DbEnv.open will return the same value to its caller.

The DbEnv.set_recovery_init interface may only be used to configure Berkeley DB before the DbEnv.open interface is called.

The DbEnv.set_recovery_init method throws an exception that encapsulates a non-zero error value on failure.

# Errors

EINVAL
  An invalid flag value or parameter was specified.

  Called after DbEnv.open was called.
