Defined in header <thread>
std::thread::id get_id()noexcept;		(since C++11)

Returns the id of the current thread.

Parameters

(none)

Return value

id of the current thread.

Example

Run this code

#include <chrono>#include <iostream>#include <syncstream>#include <thread>usingnamespace std::chrono_literals;   void foo(){std::thread::id this_id = std::this_thread::get_id();   std::osyncstream(std::cout)<<"thread "<< this_id <<" sleeping...\n";   std::this_thread::sleep_for(500ms);}   int main(){std::jthread t1{foo};std::jthread t2{foo};}

Possible output:

thread 140113018054400 sleeping... thread 140113009661696 sleeping...
