NAME

       dpns_starttrans - 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.
