std::thread::id get_id() const noexcept; |
(since C++11) | |
Returns a value of std::thread::id identifying the thread associated with *this.
Parameters
(none)
Return value
A value of type std::thread::id identifying the thread associated with *this. If there is no thread associated, default constructed std::thread::id is returned.
Example
Run this code
#include <iostream> #include <thread> #include <chrono> void foo() { std::this_thread::sleep_for(std::chrono::seconds(1)); } int main() { std::thread t1(foo); std::thread::id t1_id = t1.get_id(); std::thread t2(foo); std::thread::id t2_id = t2.get_id(); std::cout << "t1's id: " << t1_id << '\n'; std::cout << "t2's id: " << t2_id << '\n'; t1.join(); t2.join(); }
Possible output:
t1's id: 0x35a7210f t2's id: 0x35a311c4
