#include <db.h>int DBENV->set_func_dirfree(DB_ENV *dbenv, void (*func_dirfree)(char **namesp, int cnt));
The Berkeley DB library requires the ability to return any memory allocated as part of the routine which reads through a directory and creates a list of files that that the directory contains (see DBENV->set_func_dirlist). The func_dirfree argument must conform to the following interface:
int dirfree(char **namesp, int cnt);
The namesp and cnt arguments are the same values as were returned by the DBENV->set_func_dirlist function.
The func_dirfree function must return the value of errno on failure and 0 on success.
The DBENV->set_func_dirfree interface affects the entire application, not only the environment in which it is called.
The DBENV->set_func_dirfree interface may only be used to configure Berkeley DB before the DBENV->open interface is called.
The DBENV->set_func_dirfree function returns a non-zero error value on failure and 0 on success.
Called after DBENV->open was called.
