int
db_env_set_func_unlink(int (*func_unlink)(const char *path));

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

The db_env_set_func_unlink 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_unlink method 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_unlink method returns a non-zero error value on failure and 0 on success.

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