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 applications 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 argument 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 ignored.  Use _exit(2) syscall to
       terminate the process.

RETURN VALUES

       The function does not return a value.  A return from the function indicates 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.
