#include <db.h> int DB->get_re_len(DB *db, u_int32_t *re_lenp);
The DB->get_re_len() method returns the length of the records held
in a Queue access method database. This value can be set using the

called only after the database has been opened.
The DB->get_re_len()
method returns a non-zero error value on failure and 0 on success.
The DB->get_re_len() method returns the record
length in re_lenp. If the record length
has never been set using

then 0 is returned.
