PTHREAD_KILL
Section: Linux Programmer's Manual (3)
Updated: 2009-01-28
NAME
pthread_kill - send a signal to a thread
SYNOPSIS
#include <signal.h>
int pthread_kill(pthread_t thread, int sig);
Compile and link with -pthread.
DESCRIPTION
The
pthread_kill()
function sends the signal
sig
to
thread,
another thread in the same process as the caller.
The signal is asynchronously directed to
thread.
If
sig
is 0, then no signal is sent, but error checking is still performed;
this can be used to check for the existence of a thread ID.
RETURN VALUE
On success,
pthread_kill()
returns 0;
on error, it returns an error number, and no signal is sent.
ERRORS
- ESRCH
-
No thread with the ID
thread
could be found.
- EINVAL
-
An invalid signal was specified.
CONFORMING TO
POSIX.1-2001.
NOTES
Signal dispositions are process-wide:
if a signal handler is installed,
the handler will be invoked in the thread
thread,
but if the disposition of the signal is "stop", "continue", or "terminate",
this action will affect the whole process.
