     #include 

     sip_method_t sip_get_trans_method(sip_transaction_t sip_trans,
          int *error);

     const struct sip_message *sip_get_trans_orig_msg
          (sip_transaction_t sip_trans, int *error);


     const struct sip_message *sip_get_trans_resp_msg

     const struct sip_conn_object *sip_get_trans_conn_obj

     char *sip_get_trans_branchid(sip_transaction_t trans, int *error);


DESCRIPTION
     The sip_get_trans_method() function returns the  method  the
     SIP message that created the transaction sip_trans.


     The sip_get_trans_state() function returns the state of  the
     transaction sip_trans.


     A newly created transaction is in the state:
       SIP_NEW_TRANSACTION


     A client transaction  could  be  in  one  of  the  following
     states:
       SIP_CLNT_CALLING
       SIP_CLNT_INV_PROCEEDING
       SIP_CLNT_INV_TERMINATED
       SIP_CLNT_INV_COMPLETED

       SIP_CLNT_TRYING
       SIP_CLNT_NONINV_PROCEEDING
       SIP_CLNT_NONINV_TERMINATED
       SIP_CLNT_NONINV_COMPLETED


     A server transaction  could  be  in  one  of  the  following
     states:
       SIP_SRV_INV_PROCEEDING
       SIP_SRV_INV_COMPLETED
       SIP_SRV_CONFIRMED
       SIP_SRV_INV_TERMINATED
       SIP_SRV_TRYING
       SIP_SRV_NONINV_PROCEEDING
       SIP_SRV_NONINV_COMPLETED
       SIP_SRV_NONINV_TERMINATED


     The sip_get_trans_orig_msg() function  returns  the  message
     that  created  the  transaction  sip_trans.  This could be a
     request on the client or a response on the server.


     The  sip_get_trans_resp_msg()  function  returns  the   last
     response  that  was sent on the transaction sip_trans. Typi-
     cally, this response is used by the  transaction  layer  for
     retransmissions  for unreliable transports or for responding
     to retransmitted requests.  A  response  that  terminates  a
     transaction is not returned.


     The sip_get_trans_conn_obj()  function  returns  the  cached
     connection object, if any, in the transactionsip_trans.


     The sip_get_trans_branchid() function returns the branch  ID
     for  the  message that created the transactionsip_trans. The
     caller is responsible for freeing the returned string.

RETURN VALUES
     The   sip_get_trans_orig_msg(),    sip_get_trans_resp_msg(),
     sip_get_trans_conn_obj(), and sip_get_trans_branchid() func-
     tions return the  required  value  on  success  or  NULL  on
     failure.


     The sip_get_trans_state() and  sip_get_trans_method()  func-
     tions  return  the  required  value  on  success  and  -1 on
     failure.

     The value of errno is not changed  by  these  calls  in  the
     event of an error.

ERRORS
     If the error is non-null, one of  the  following  values  is
     set:

     EINVAL    The input transaction sip_trans is NULL.


     ENOMEM    For sip_get_trans_branchid() there  is  an   error
               allocating memory for the branch ID string.



     On success, the value of the location pointed to by error is
     set to 0.
