_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

_lwp_kill(2)							   System Calls 						      _lwp_kill(2)

NAME
_lwp_kill - send a signal to a LWP SYNOPSIS
#include <sys/lwp.h> #include <signal.h> int _lwp_kill(lwpid_t target_lwp, int sig); DESCRIPTION
The _lwp_kill() function sends a signal to the LWP specified by target_lwp. The signal that is to be sent is specified by sig and must be one from the list given in signal.h(3HEAD). If sig is 0 (the null signal), error checking is performed but no signal is actually sent. This can be used to check the validity of target_lwp. The target_lwp must be an LWP within the same process as the calling LWP. RETURN VALUES
Upon successful completion, 0 is returned. A non-zero value indicates an error. ERRORS
If any of the following conditions occur, _lwp_kill() fails and returns the corresponding value: EINVAL The sig argument is not a valid signal number. ESRCH The target_lwp argument cannot be found in the current process. ATTRIBUTES
