int db_env_set_func_rename(int (*func_rename)(int fd));
Replace Berkeley DB calls to the IEEE/ANSI Std 1003.1 (POSIX) rename function with func_rename, which must conform to the standard interface.
The db_env_set_func_rename interface affects the entire application, not a single database or database environment.
Although the db_env_set_func_rename 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_rename function returns a non-zero error value on failure and 0 on success.
The db_env_set_func_rename function may fail and return a non-zero error for the following conditions:
The db_env_set_func_rename function 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_rename function may fail and return DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
