PTHREAD_KILL(3P) POSIX Programmer's Manual PTHREAD_KILL(3P)
This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior), or
the interface may not be implemented on Linux.
pthread_kill — send a signal to a thread
#include <signal.h>
int pthread_kill(pthread_t thread, int sig);
The pthread_kill() function shall request that a signal be delivered
to the specified thread.
As in kill(), if sig is zero, error checking shall be performed but
no signal shall actually be sent.
Upon successful completion, the function shall return a value of
zero. Otherwise, the function shall return an error number. If the
pthread_kill() function fails, no signal shall be sent.
The pthread_kill() function shall fail if:
EINVAL The value of the sig argument is an invalid or unsupported
signal number.
The pthread_kill() function shall not return an error code of
[EINTR].
The following sections are informative.
None.
The pthread_kill() function provides a mechanism for asynchronously
directing a signal at a thread in the calling process. This could be
used, for example, by one thread to affect broadcast delivery of a
signal to a set of threads.
Note that pthread_kill() only causes the signal to be handled in the
context of the given thread; the signal action (termination or
stopping) affects the process as a whole.
If an implementation detects use of a thread ID after the end of its
lifetime, it is recommended that the function should fail and report
an [ESRCH] error.
None.
