THR_EXIT(2)		    BSD	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), thr_kill(2), thr_kill2(2), thr_new(2), thr_self(2),
     thr_set_name(2), _umtx_op(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.
