If application-specific allocation routines have been declared (see <a href="../../db46-devel-4.6.21/api_cxx/env_set_alloc.html">DbEnv::set_alloc</a> for more information), they are used to allocate the memory; otherwise, the standard C library <b>malloc</b>(3) is used. The caller is responsible for deallocating the memory. To deallocate the memory, free the memory reference; references inside the returned memory need not be individually freed.</p> <p>The following DB_REPMGR_SITE fields will be filled in:</p> <dl compact> <dt>int eid;<dd>Environment ID assigned by the replication manager.
