#include <db_cxx.h>
int
DbEnv::repmgr_site_list(u_int *countp, DB_REPMGR_SITE **listp);
Description: DbEnv::repmgr_site_list
The DbEnv::repmgr_site_list method returns the status of the sites currently
known by the replication manager.
The DbEnv::repmgr_site_list method creates a statistical structure of type
DB_REPMGR_SITE and copies a pointer to it into a user-specified memory
location.
Statistical structures are stored in allocated memory. If application-specific allocation
routines have been declared (see DbEnv::set_alloc for more
information), they are used to allocate the memory; otherwise, the
standard C library malloc(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.
The following DB_REPMGR_SITE fields will be filled in:
int eid;- Environment ID assigned by the replication manager.
This is the same value that is passed to the application's
event notification function for the DB_EVENT_REP_NEWMASTER event.
char host[];- Nul-terminated host name.
u_int port;
u_int32_t status;
The DbEnv::repmgr_site_list method may be called at any time during the life of the
application.
The DbEnv::repmgr_site_list 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.
Parameters
countp- A count of the returned structures will be stored into the memory
referenced by countp.
listp- A reference to an array of structures will be stored into the memory
referenced by listp.
