Hello everyone,
I am searching and searching and can't find an answer.
I try to register a sighandler in my extension's C code. But my
sighandler is never called. Is there anything preventing extensions to
receive signals?
I register like this:
[.. some code that works ..]
// register the sigint listeners.
if (signal(SIGTERM, killReceiver) == SIG_ERR) {
printf("2 An error occurred while setting a signal
handler.%s\n", stderr);
}
if (signal(SIGHUP, killReceiver) == SIG_ERR) {
printf("3 An error occurred while setting a signal
handler.%s\n", stderr);
}
if (signal(SIGINT, killReceiver) == SIG_ERR) {
printf("4 An error occurred while setting a signal
handler.%s\n", stderr);
}
[.. even more code that works ..]
handler code:
static void killReceiver(int signum){
printf("Cleaning up\n");
}
When I exit R, my signal handler is not being called. Am I listening
to the right signals? Do I have some misunderstanding on my side?
Funny side story, if I manually raise(SIGINT), my handlers gets called.
Thanks for some light on this,
Ulrich
