[reSIProcate] how to get "char *sdp_string" from "SdpContents sdp"?

[Kenneth Ho]

something like this:

#include <resiprocate/SdpContents.hxx>
#include <sstream>
#include <string>

void foo (const SdpContents& sdp)
{
  std::ostringstream buf;
  buf << sdp;
  std::string txt(buf.str());
  // do whatever you need to with *txt*
}
