A Simple Thread Example


#include <pthread.h>
#include <stdio.h>

#define NUM_THREADS 5

void *PrintHello(void* threadid)
{
int tid;
tid = (int)threadid;

printf("#####Hello World! It's me, thread #%ld!\n", tid);
pthread_exit(NULL);
}

int main (int argc, char *argv[])
{
pthread_t threads[NUM_THREADS];

int rc;
int t;

for(t=0; t<NUM_THREADS; t++){
printf("In main: creating thread %ld\n", t);
rc = pthread_create(&threads[t], NULL, PrintHello, (void *)t);

//rc = pthread_create(&threads[t], NULL, PrintHello, t);

if (rc){
printf("ERROR; return code from pthread_create() is %d\n", rc);
exit(-1);
}
}
pthread_exit(NULL);
}
