dpns_starttrans(3) start transaction mode

SYNOPSIS

#include <sys/types.h>
#include "dpns_api.h"

int dpns_starttrans (char *server, char *comment);

DESCRIPTION

dpns_starttrans starts transaction mode. The connection to the Name Server is kept open until one of the DB update operation fails or dpns_aborttrans or dpns_endtrans is explicitly called. If all the DB update operations between dpns_starttrans and dpns_endtrans are successful, a COMMIT is done. If any DB update operation fails or if an explicit dpns_aborttrans is done, a ROLLBACK is done. The comment is logged in the server log.

RETURN VALUE

This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

ERRORS

EINVAL
The length of comment exceeds CA_MAXCOMMENTLEN.
SENOSHOST
Host unknown.
SENOSSERV
Service unknown.
SECOMERR
Communication error.
ENSNACT
Name server is not running or is being shutdown.
