如何不使用pthread_cancel而杀死线程
During the time I use standalone cross compliers to build my system, I find there is NO pthread_cancel in pthread.h (/home/dengwei/standalone-toolchain/sysroot/usr/include/pthread.h).
Shocked by that, but here comes the solution, by using pthread_kill to send a signal , and adding a signal handler :
#include
#include
#include
#include
#include
#include
#include
pthread_t pid;
void handle_quit(int signo)
{
printf("in qq handle sig %d \n", signo);
pthread_exit(NULL);
}
void* test(void *arg)
{
signal(SIGQUIT,handle_quit );
for(int i=0;i<100;i++)
{
printf("in pthread test \n");
sleep(1);
}
}
int main(void)
{
printf("begin \n");
pthread_create(&pid, NULL , test, NULL);
sleep(3);
if(pthread_kill(pid, 0)!= ESRCH)
{
printf("thread %d exists!\n", pid);
pthread_kill(pid, SIGQUIT);
// pthread_exit(NULL);//this won't work
printf("after kill\n");
}
sleep(1);
printf("exit in main\n");
}
