int
db_env_set_func_dirlist(
int (*func_dirlist)(const char *dir, char ***namesp, int *cntp));
Description
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 db_env_set_func_dirlist interface affects the entire application, not a single
database or database environment.
While the db_env_set_func_dirlist 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_dirlist interface may only be used to configure Berkeley DB before
the DBENV->open interface is called.
The db_env_set_func_dirlist function returns a non-zero error value on failure and 0 on success.
