NAME
     sip_delete_start_line,                    sip_delete_header,
     sip_delete_header_by_name,  sip_delete_value  - delete a SIP
     header or a header value

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

     int sip_delete_start_line(sip_msg_t sip_msg);


     int sip_delete_header(sip_msg_t sip_header);


     int sip_delete_header_by_name(sip_msg_t msg,
          char *header_name);


     int sip_delete_value(sip_header_t sip_header,
          sip_header_value_t sip_header_value);


DESCRIPTION
     The sip_delete_start_line() function deletes the start line,
     a request or a response line, from the SIP message sip_msg.


     The sip_delete_header()  function  deletes  the  SIP  header
     specified  by  sip_header  from  the  associated SIP message
     sip_msg.


     The sip_delete_header_by_name()  function  deletes  the  SIP
     header  name specified by header_name (long or compact form)
     from the SIP message sip_msg.


     The sip_delete_value() deletes the SIP header  value  speci-
     fied by sip_header_value from the SIP header sip_header.


     When a SIP header or value  is  deleted,  the  corresponding
     header  or  value  is  marked  as  deleted.   Lookups ignore
     headers or values that are marked as deleted.

RETURN VALUES
     These functions return 0  on  success  and  the  appropriate
     error on failure.
