_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. ATTRIBUTES
