GETTID

Section: Linux Programmer's Manual (2)
Updated: 2014-02-11

NAME

gettid - get thread identification  

SYNOPSIS

#include <sys/types.h>

pid_t gettid(void);

Note: There is no glibc wrapper for this system call; see NOTES.  

DESCRIPTION

gettid() returns the caller's thread ID (TID). In a single-threaded process, the thread ID is equal to the process ID (PID, as returned by getpid(2)). In a multithreaded process, all threads have the same PID, but each one has a unique TID. For further details, see the discussion of CLONE_THREAD in clone(2).  

RETURN VALUE

On success, returns the thread ID of the calling process.  

ERRORS

This call is always successful.  

VERSIONS

The gettid() system call first appeared on Linux in kernel 2.4.11.  

CONFORMING TO

gettid() is Linux-specific and should not be used in programs that are intended to be portable.  

NOTES

Glibc does not provide a wrapper for this system call; call it using syscall(2).

The thread ID returned by this call is not the same thing as a POSIX thread ID (i.e., the opaque value returned by pthread_self(3)).  

SEE ALSO

capget(2), clone(2), fcntl(2), fork(2), get_robust_list(2), getpid(2), ioprio_set(2), perf_event_open(2), sched_setaffinity(2), sched_setparam(2), sched_setscheduler(2), tgkill(2), timer_create(2)
