does c++ support multithreading code example
Example: c++ multithreading
#include <iostream>
#include <cstdlib>
#include <pthread.h>
using namespace std;
#define NUM_THREADS 5
void *PrintHello(void *threadid) {
long tid;
tid = (long)threadid;
cout << "Hello World! Thread ID, " << tid << endl;
pthread_exit(NULL);
}
int main () {
pthread_t threads[NUM_THREADS];
int rc;
int i;
for( i = 0; i < NUM_THREADS; i++ ) {
cout << "main() : creating thread, " << i << endl;
rc = pthread_create(&threads[i], NULL, PrintHello, (void *)i);
if (rc) {
cout << "Error:unable to create thread," << rc << endl;
exit(-1);
}
}
pthread_exit(NULL);
}
