GETTID(2) Linux Programmer's Manual GETTID(2)
gettid - get thread identification
gettid returns the thread ID of the current process. This
is equal to the process ID (as returned by getpid(2)),
unless the process is part of a thread group (created by
specifying the CLONE_THREAD flag to the clone(2) system
call). All processes in the same thread group have the
same PID, but each one has a unique TID.
gettid is Linux specific and should not be used in pro-
grams that are intended to be portable.
