Pass integer value through pthread_create

Question

I simply want to pass the value of an integer to a thread.

How can I do that?

I tried:

    int i;
    pthread_t thread_tid[10];
    for(i=0;          


        

Answer 1

int is 32 bit, and void * is 64 bit in 64bit Linux; In that case you should use long int instead of int;

long int i;
pthread_create(&thread_id, NULL, fun, (void*)i);

int fun(void *i) function

 long int id = (long int) i;
