How to get results in case of POST method

Hi Friends,

I am new to libwww. I have written a POST request (In C) for
sending usename and password for simple login. the result of
this request is an XML file, but I don't know how to get and
display it in case of POST. I have used
HTPostFormAnchorToChunk method and after it, I am trying to
store it in a string using HTChunk_toCString, but I am getting
an empty string. Please guide.

Neelu.
