THR_EXIT(2)		      System Calls Manual		   THR_EXIT(2)

NAME
       thr_exit	-- terminate current thread

LIBRARY
       Standard	C Library (libc, -lc)

SYNOPSIS
       #include	<sys/thr.h>

       void
       thr_exit(long *state);

DESCRIPTION
       This  function is intended for implementing threading.  Normal applica-
       tions should call pthread_exit(3) instead.

       The thr_exit() system  call  terminates	the  current  kernel-scheduled
       thread.

       If the state argument is	not NULL, the location pointed to by the argu-
       ment  is	 updated  with an arbitrary non-zero value, and	an _umtx_op(2)
       UMTX_OP_WAKE operation is consequently performed	on the location.

       Attempts	to terminate the last thread in	the process are	 silently  ig-
       nored.  Use _exit(2) syscall to terminate the process.

RETURN VALUES
       The function does not return a value.  A	return from the	function indi-
       cates that the calling thread was the last one in the process.

SEE ALSO
       _exit(2),    _umtx_op(2),    thr_kill(2),   thr_kill2(2),   thr_new(2),
       thr_self(2), thr_set_name(2), pthread_exit(3)

STANDARDS
       The thr_exit() system call is non-standard and is used by 1:1 Threading
       Library (libthr,	-lthr) to implement IEEE Std  1003.1-2001  ("POSIX.1")
       pthread(3) functionality.

HISTORY
       The thr_exit() system call first	appeared in FreeBSD 5.2.

FreeBSD	13.2			  May 5, 2020			   THR_EXIT(2)
