Name of running threads inside a process

Question

I have a parent process which creates a thread for each client like this:

pthread_create(&thread, NULL, interact, bundle);

Then I rename each tread with:

pthread_setname_np(thread, "some name");

Running command "ps uH p " in my linux terminal, I will get thread details currently running in the parent process, but it doesn't provide the names I just assigned to them.

Is there any specific command to run and get thread names?

Answer 1

As hinted at in the pthread_setname_np , the new name is accessible as ps format specifier comm , but not args or command (which is what is usually printed):

ps H -C <cmd name> -o 'pid tid args comm'

illustrates the difference (adapted from the man page). I haven't been able to find a good piece of documentation that discusses this explicitly, though.

Here, <cmd name> is the name of your program's binary.
