pthread_kill - send a signal to a thread
#include <signal.h>int pthread_kill(pthread_t thread, int sig);
Compile and
link with -pthread.
Feature Test Macro Requirements for glibc (see feature_test_macros(7)
):
pthread_kill():
_POSIX_C_SOURCE >= 199506L || _XOPEN_SOURCE >= 500
The
pthread_kill() function sends the signal sig to thread, a 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.
On success, pthread_kill() returns 0; on error, it returns
an error number, and no signal is sent.
- EINVAL
- An invalid signal was
specified.
The pthread_kill()
function is thread-safe.
POSIX.1-2008.
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.
POSIX.1-2008 recommends that if an implementation detects the use of a thread
ID after the end of its lifetime, pthread_kill() should return the error
ESRCH. The glibc implementation returns this error in the cases where an
invalid thread ID can be detected. But note also that POSIX says that an
attempt to use a thread ID whose lifetime has ended produces undefined
behavior, and an attempt to use an invalid thread ID in a call to pthread_kill()
can, for example, cause a segmentation fault.
