Name
gettid — get thread identification
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.
RETURN VALUE
On success, returns the thread ID of the current
process.
ERRORS
This call is always successful.
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).
SEE ALSO
clone(2), fork(2), getpid(2)
