GETTID(2) Linux Programmer's Manual GETTID(2)

NAME
gettid - get thread identification

SYNOPSIS
#include <sys/types.h>
#include <linux/unistd.h>

_syscall0(pid_t,gettid)

pid_t gettid(void);

DESCRIPTION
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.

CONFORMING TO
gettid is Linux specific and should not be used in pro­
grams that are intended to be portable.

SEE ALSO
getpid(2), clone(2), fork(2)
