gettid
GETTID(2) Linux Programmer's Manual GETTID(2)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 dis-
cussion 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)).
