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;

It better to use of a struct for send more parameters in one :

struct PARAMS
{
    int i;
    char c[255];
    float f;
} params;

pthread_create(&thread_id, NULL, fun, (void*)(¶ms));

then you can cast params to PARAMS* and use of it in pthread routine:

PARAMS *p = static_cast(params);
p->i = 5;
strcpy(p->c, "hello");
p->f = 45.2;
