#include <db.h>

int
db_env_set_func_free(void (*func_free)(void *ptr));

Description

Replace Berkeley DB calls to the ANSI C X3.159-1989 (ANSI C) standard free interface with func_free, which must conform to the standard interface.

The db_env_set_func_free method configures all operations performed by a process and all of its threads of control, not operations confined to a single database environment.

Although the db_env_set_func_free interface may be called at any time during the life of the application, it should normally be called before making calls to the db_env_create or db_create methods.

The db_env_set_func_free method returns a non-zero error value on failure and 0 on success.

Errors

The db_env_set_func_free method 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_func_free method 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_func_free method may fail and return DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
