db_env_set_func_realloc(void *(*func_realloc)(void *ptr, size_t size));
Replace Berkeley DB calls to the ANSI C X3.159-1989 (ANSI C) standard
realloc interface with func_realloc, which must conform to
the standard interface.
The db_env_set_func_realloc method configures all operations performed by a process and
all of its threads of control, not operations confined to a single
Although the db_env_set_func_realloc 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_realloc method returns a non-zero error value on failure and 0 on success.
The db_env_set_func_realloc method may fail and return a non-zero error for the following conditions:
- An invalid flag value or parameter was specified.
The db_env_set_func_realloc 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_realloc method may fail and
in which case all subsequent Berkeley DB calls will fail in the same way.
