db_env_set_func_open

#include <db.h>

int
db_env_set_func_open(int (*func_open)(const char *path, int flags, 
    int mode)); 

Replace Berkeley DB calls to the IEEE/ANSI Std 1003.1 (POSIX) open function with func_open, which must conform to the standard interface specification.

The db_env_set_func_open() function 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_open() function 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_open() function returns a non-zero error value on failure and 0 on success.

Parameters

func_open

The func_open parameter is the replacement function. It must conform to the standard interface specification.
