[SIPForum-discussion] Pls guide me

[hemanth kumar]

Hi,
   
  SIP message is a string and a string would end with '\0'. Read section 25 in RFC 3261 to understand ABNF grammar, which gives a clear idea on how the message should be parsed. 
   
  Simplest way: Each line in SIP message would end with '\r\n' (except for the content-length header) which could be used as delimiter.
   
  Standard way: Use parsers and lexical analysers like bison and flex
   
  Hope this helps

  Hi All,

This is Hariprasad.

I am writing a program to decode a sip messge.

I have a question that,
in the sip message '\0' or NULL characters will be there?

Because i am decoding the message based on assuming that there wont be
such NULL characters.

Please guide me in this..
Thanks
Hari
