NAME
     sip_get_request_method,               sip_get_response_code,
     sip_get_response_phrase, sip_get_sip_version - obtain attri-
     butes from the start line in a SIP message

SYNOPSIS
     cc [ flag ... ] file ... -lsip [ library ... ]
     #include 

     sip_method_t sip_get_request_method(const sip_msg_t sip_msg,
          int *error);


     int sip_get_response_code(sip_msg_t sip_msg,
          int *error);


     const sip_str_t *sip_get_response_phrase(sip_msg_t sip_msg,
          int *error);


     const sip_str_t*sip_get_sip_version(sip_msg_t sip_msg,
          int *error);


DESCRIPTION
     For functions that  return  a  pointer  of  type  sip_str_t,
     sip_str_t is supplied by:

       typedef struct sip_str {
            char *sip_str_ptr;
            int  sip_str_len;
       }sip_str_t;



     The  sip_str_ptr  parameter  points  to  the  start  of  the
     returned  value  and  sip_str_len supplies the length of the
     returned value.


     For example, given the following request line in a SIP  mes-
     sage sip_msg that is input to sip_get_request_uri_str():

       FROM : ;tag=1928301774



     the return is a pointer to sip_str_t  with  the  sip_str_ptr
     member pointing to "A" of Alice and sip_str_len being set to
     5, the length of Alice.

     Access functions for headers that can have  multiple  values
     take  the value as the input, while those that can have only
     one value take the SIP message sip_msg as the input.


     The sip_get_request_method() function will  return  the  SIP
     method  from  the  request line in the  SIP message sip_msg.
     The method can be one of the following:
       INVITE
       ACK
       OPTIONS
       BYE
       CANCEL
       REGISTER
       REFER
       INFO
       SUBSCRIBE
       NOTIFY
       PRACK
       UNKNOWN


     The  sip_get_response_code()  function   will   return   the
     response  code  response  from  the request line in the  SIP
     message sip_msg.


     The  sip_get_respose_phrase()  function  will   return   the
     response  phrase  response from the request line in the  SIP
     message sip_msg.


     The sip_get_sip_version() function will return  the  version
     of the SIP protocol from the request or the response line in
     the SIP message sip_msg.

RETURN VALUES
     For functions that return a pointer to sip_str_t, the return
     value  is  the specified value on success or NULL in case of
     error. For functions that  return  an  integer,  the  return
     value is the specified value on success and -1 on error.


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

ERRORS
     These functions take a pointer to an  integer  error  as  an
     argument.  If  the  error  is non-null, one of the following
     values is set:

     EINVAL    The input SIP message sip_msg or the header  value
               is  null;  or the specified header/header value is
               deleted.


     EPROTO    The header value is not present  or  invalid.  The
               parser could not parse it correctly.


     ENOMEM    There is an error allocating memory for the return
               value.



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