Db::get_q_extentsize(u_int32_t *extentsizep);

The Db::get_q_extentsize() method returns the number of pages in an extent. This value is used only for Queue databases and is set using the Db::set_q_extentsize() method.

The Db::get_q_extentsize() method may be called only after the database has been opened.

The Db::get_q_extentsize() method either returns a non-zero error value or throws an exception that encapsulates a non-zero error value on failure, and returns 0 on success.
