_LWP_KILL(2) System Calls _LWP_KILL(2)

_lwp_kill - send a signal to a LWP

#include <sys/lwp.h>
#include <signal.h>
int _lwp_kill(lwpid_t target_lwp, int sig);

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.

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

If any of the following conditions occur, _lwp_kill() fails and returns the corresponding value:


The sig argument is not a valid signal number.


The target_lwp argument cannot be found in the current process.
