arkadaşlar kodum şu
#include <stdio.h>
#include <pthread.h>
pthread_mutex_t mutex;
void *thread_f(void *args)
{
int xyz;
xyz=(int)args;
pthread_mutex_lock(&mutex);
if(xyz==1)
printf("\nT1");
else if(xyz==2)
printf("\nT2");
else if(xyz==3)
printf("\nT3");
pthread_mutex_unlock(&mutex);
pthread_exit(NULL);
}
void *scheduler(void *args)
{
int i=0;
int x=1,y=2,z=3;
pthread_t t1,t2,t3;
pthread_attr_t myAttr;
pthread_attr_init(&myAttr);
pthread_attr_setschedpolicy(&myAttr,SCHED_FIFO);
for(i=0;i<10;i++)
{
pthread_create(&t1,&myAttr,thread_f,&x);
pthread_create(&t2,&myAttr,thread_f,&y);
pthread_create(&t3,&myAttr,thread_f,&z);
pthread_join(t1,NULL);
pthread_join(t2,NULL);
pthread_join(t3,NULL);
}
pthread_exit(NULL);
}
main(void)
{
pthread_t thr;
pthread_mutex_init(&mutex,NULL);
pthread_create(&thr,NULL,scheduler,NULL);
pthread_join(thr,NULL);
}
bunun içinde scheduler ve main içindeki pthread_create ve pthread_join'lerde bi problem var sanırım.
problem tam olarak şu
