How to get thread id in C++ process?

Question

C++ / C#

How to get id and handles of all threads running only in C++ code? That is, only those threads that were created during the execution of the program.

Answer 1

It is possible to get a list of all threads of one process via Thread32First/Thread32Next ( example ).
It is looked for in Google literally on "winapi list threads".

Answer 2

If you create them, then the easiest way is to remember what you created there.
For example:
for std::thread there is std::thread::id get_id() const noexcept
for CreateThread - the last parameter is a pointer where to add id
for pthread_create - the first parameter is a pointer to pthread_t where id will be added on success
