SIGLWP signal is used as an inter-LWP signaling mechanism when directed to particular LWPs within the process via the _lwp_kill() interface. It is reserved for the threads packages.

SIGWAITING signal is generated by the kernel when it detects that all the LWPs in the process have blocked in indefinite waits. It is used by threads packages to ensure that processes don't deadlock indefinitely due to lack of execution resources.

_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
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |MT-Level |Async-Signal-Safe | +-----------------------------+-----------------------------+ SEE ALSO
kill(2), sigaction(2), sigprocmask(2), signal.h(3HEAD), attributes(5) SunOS 5.10 8 Aug 2001 _lwp_kill(2)
