sys_gettid [kernel/timer.c]

This is equal to the process ID (as returned by sys_getpid), unless the process is part of a thread group (created by specifying the CLONE_THREAD flag to the sys_clone system call). All processes in the same thread group have the same PID, but each one has a unique TID. Arguments
