Setting the thread /proc/PID/cmdline?

Question

On Linux/NPTL, threads are created as some kind of process.

I can see some of my process have a weird cmdline:

cat /proc/5590/cmdlin         


        

Answer 1

Bah.. the code is not that nice, the trick is to reuse the environ (here argv_buffer) pointer:

memset (argv_buffer[0] + len, 0, argv_size - len);
argv_buffer[1] = NULL;

Any better idea?

Is that working for different threads?
