    #include <db.h>

    int
    db_env_set_func_malloc(void *(*func_malloc)(size_t size));

# Description

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

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

# Errors

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