Question

i’m in a situation where i need to get boost::thread::id into a variable, but this variable is NOT a string, neither a string operation is allowed. is that possible?

maybe something like

char *tid = (casting something) boost::this_thread::get_id()

this is c++ on unix system.
the reason why avoiding using string operation is because it slows down the whole application speed. thanks before.

What about:

std::ostringstream oss;
oss << boost::thread::get_id();
std::string idAsString = oss.str();

See the documentation on boost::thread::id

Update:
Since you already use boost, why not use:

std::string id = boost::lexical_cast<std::string>(boost::thread::get_id());

Also, as you are doing this only at the beginning speed should not be an issue.
