#include <db.h>int DBENV->set_func_dirlist(DB_ENV *dbenv, int (*func_dirlist)(const char *dir, char ***namesp, int *cntp));
The Berkeley DB library requires the ability to read through a directory and create a list of files that that the directory contains. The func_dirlist argument must conform to the following interface:
int dirlist(const char *dir, char ***namesp, int *cntp);
The dir argument is the name of the directory to be searched. The function must return a pointer to an array of nul-terminated file names in the memory location referenced by the argument namesp, and a count of the number of elements in the array in the memory location referenced by cntp.
The func_dirlist function must return the value of errno on failure and 0 on success.
The DBENV->set_func_dirlist interface affects the entire application, not only the environment in which it is called.
The DBENV->set_func_dirlist interface may only be used to configure Berkeley DB before the DBENV->open interface is called.
The DBENV->set_func_dirlist function returns a non-zero error value on failure and 0 on success.
Called after DBENV->open was called.
