_lwp_suspend(2) 						   System Calls 						   _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_sus-
       pend(), target_lwp is no longer executing. Once a thread is suspended, subsequent 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_con-
       tinue() 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.
