Quit from thread loop epoll

Hello,
I need a better way to quit from the thread loop without changing epoll timeout(-1) or creating a dummy socket

test.c

#include <stdio.h>
#include <pthread.h>
#include <sys/epoll.h>
#include <sys/socket.h>
#include <sys/un.h>
#include <unistd.h>

#define SOCKNAME "/tmp/blah.socket"

int sock = -1,running;

void* myth(void* arg) {
	struct epoll_event ev,events[1];
	int efd = epoll_create1(0);
        ev.events = EPOLLIN;
        ev.data.fd = sock;
        if (epoll_ctl(efd, EPOLL_CTL_ADD,sock, &ev) < 0) return NULL;
	int nc = 1;
	while(running){
		printf("waiting ...\n");
		int nfd = epoll_wait(efd,events,nc,-1);
		if (nfd == -1) break;
		
		for (int i = 0; i < nfd; i++) {
			//code
		}
	}
	printf("closing \n");
	close(efd);
	return NULL;
}

int init_socket(const char *s){
	struct sockaddr_un sa;
	unlink(s);
	int sck = socket(AF_UNIX, SOCK_STREAM, 0);
	sa.sun_family = AF_UNIX;
	strcpy(sa.sun_path,s);
	if (bind(sck,(const struct sockaddr *)&sa,(socklen_t)sizeof(sa)) <0) {
		return -1;
	}
	if (listen(sck,5) < 0 )return -1;
	return sck;
}

int main(){
	pthread_t th;
	sock = init_socket(SOCKNAME);
	running = 1;
	pthread_create(&th,NULL,myth,NULL);
	sleep(3);
	running = 0;
	
	struct sockaddr_un sa;
	int sock1 = socket(AF_UNIX,SOCK_STREAM, 0);
	sa.sun_family = AF_UNIX;
	strcpy(sa.sun_path,SOCKNAME);
	connect(sock1,(const struct sockaddr *)&sa,sizeof(sa));
	
	printf("joining ...\n");
	pthread_join(th,NULL);
	close(sock1);
	close(sock);
	printf("closed\n");
	return 0;
}

gcc -o test test.c -lpthread

Thanks.

Hm. I think the usual way is to set running to 0.
Otherwise please use:

gcc -pthread -o test test.c # no -lpthread

Thanks, I'll check that.
