_LWP_SUSPEND(2)						       _LWP_SUSPEND(2)

NAME
       _lwp_suspend, _lwp_continue - continue or suspend LWP execution

SYNOPSIS
       #include <sys/lwp.h>

       int _lwp_suspend(lwpid_t target_lwp);

       int _lwp_continue(lwpid_t target_lwp);

DESCRIPTION
       The  _lwp_suspend()  function immediately suspends the execution of the
       LWP specified by target_lwp. On successful return from  _lwp_suspend(),
       target_lwp  is  no longer executing. Once a thread is suspended, subse‐
       quent calls to _lwp_suspend() have no affect.

       The _lwp_continue() function resumes the execution of a suspended  LWP.
       Once  a suspended LWP is continued, subsequent calls to _lwp_continue()
       have no effect.

       A suspended LWP will not be awakened by	a  signal.  The	 signal	 stays
       pending until the execution of the LWP is resumed by _lwp_continue().

RETURN VALUES
       Upon  successful	 completion, 0 is returned. A non-zero value indicates
       an error.

ERRORS
       If the following condition occurs, _lwp_suspend()  and  _lwp_continue()
       fail and return the corresponding value:

       ESRCH
		The  target_lwpid  argument  cannot  be	 found	in the current
		process.
