int
db_env_set_func_dirfree(void (*func_dirfree)(char **namesp, int cnt));
Description
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 db_env_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 db_env_set_func_dirlist function.
The func_dirfree function must return the value of errno on
failure and 0 on success.
The db_env_set_func_dirfree interface affects the entire application, not a single
database or database environment.
While the db_env_set_func_dirfree 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_dirfree interface may only be used to configure Berkeley DB before
the DBENV->open interface is called.
The db_env_set_func_dirfree function returns a non-zero error value on failure and 0 on success.
