Converting a boost:thread::id type to std long.

I am creating a warpper for the boost::thread class. Many of our users do not like the boost's own types. So I have this function in my classs

long getId();

to give the users in std types.

The getId() simply get the id of the composed boost::thread object within my class. But the problem is boost::thread return their own type boost::thread::id when I call call the get_id() of the boost::thread . I want to oconvert this to long in my getId() functiion. So in essence...

how to convert

boost::thread::id to long?

Don't do that, since it is not a thread ID. Depending on which platform your code is running, it is either a encapsulated 'pthread_t*' or a Windows HANDLE (see boost/thread/pthread/thread_data.hpp or boost/thread/win32/thread_data.hpp respectively).

In out application we need some kind of an ID returned from the wrapper. therefore I tried doing a reinterpret_cast from boos::thread::id to long. It did not work.

That won't work since thread::id is a class and not a POD. There however is on operator for ostreams, so the following should work:

#include <sstream>

long thread_id_to_long(const boost::thread::id& tid) {

  long l;
  std::stringstream ss;

  ss << id;

  ss >> l;

  return l;
}
