    int
    db_env_set_func_realloc(void *(*func_realloc)(void *ptr, size_t size));

# Description

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

The db_env_set_func_realloc interface affects the entire application, not a single database or database environment.

While the db_env_set_func_realloc interface may be used to configure Berkeley DB at any time during the life of the application, it should normally be called before making any calls to the db_env_create or db_create functions.

The db_env_set_func_realloc function returns a non-zero error value on failure and 0 on success.

# Errors

EINVAL
  An invalid flag value or parameter was specified.
