PTHREAD_KILL(2) System Calls Manual PTHREAD_KILL(2)

pthread_killsend a signal to a specified thread

#include <signal.h>

int
pthread_kill(pthread_t thread, int sig);

The () function sends a signal, specified by sig, to a thread, specified by thread. If sig is 0, error checking is performed, but no signal is actually sent.

If successful, pthread_kill() returns 0. Otherwise, an error number is returned.

The pthread_kill() function will fail if:

[]
thread is an invalid thread ID.
[]
sig is an invalid or unsupported signal number.
[]
thread was not created by pthread_create() and does not support being killed with pthread_kill()

#include <pthread.h> #include <signal.h>

The include file <pthread.h> is necessary.
