Tetsuo, I can't provide further comment because my knowledge is limited too. Somehow, I don't know the real reason why the kernel developers choose to do that way. Perhaps, CC-ing your question to LKML will pull better explanation? > current->pid should be used for /proc/<pid> directory > and > current->tgid should be used for /proc/<pid>/task/<tid> directory > for 2.6 kernels? Hey, I just know that /proc/<pid>/task/<tid> exists :) stupid me...thanks for the info! I'll take a look on it... regards Mulyadi -- Kernelnewbies: Help each other learn about the Linux kernel.
