Description: DB_ENV-&gt;rep_set_priority
The DB_ENV-&gt;rep_set_priority method specifies the database environment's
priority in replication group elections. A special value of
0 indicates that this environment cannot be a replication
group master.
The database environment's replication subsystem may also be configured using the
environment's <a href="../../db4-devel-4.7.25/ref/env/db_config.html#DB_CONFIG">DB_CONFIG</a> file. The syntax of the entry in that
file is a single line with the string "rep_set_priority", one or more whitespace
characters, and the priority of this site.
For example, "rep_set_priority 1" sets the priority of this site to 1.
Because the <a href="../../db4-devel-4.7.25/ref/env/db_config.html#DB_CONFIG">DB_CONFIG</a> file is read when the database environment
is opened, it will silently overrule configuration done before that
time.
The DB_ENV-&gt;rep_set_priority method configures a database environment, not only operations
performed using the specified <a href="../../db4-devel-4.7.25/api_c/env_class.html">DB_ENV</a> handle.
The DB_ENV-&gt;rep_set_priority method may be called at any time during the life of the
application.
The DB_ENV-&gt;rep_set_priority method
returns a non-zero error value on failure
and 0 on success.

Parameters 
 priority<ul compact><li>The priority of this database environment in the replication group. The
priority must be a non-zero integer, or 0 if this environment cannot be
a replication group master. (See <a href="../../db4-devel-4.7.25/ref/rep/pri.html">Replication environment priorities</a> for more information).</ul>

Description: DB_ENV-&gt;rep_get_priority
The DB_ENV-&gt;rep_get_priority method returns the database environment priority.
The DB_ENV-&gt;rep_get_priority method may be called at any time during the life of the
application.
The DB_ENV-&gt;rep_get_priority method
returns a non-zero error value on failure
and 0 on success.

Parameters 
 priorityp<ul compact><li>The DB_ENV-&gt;rep_get_priority method returns the
database environment priority in priorityp.</ul>
