C++ (Cpp) bbs_rand Examples

Example #1

int main(int argc, char *argv[])
{
    unsigned char *seed;
    unsigned int   ix, num = 1;
    pid_t          pid;

    if(argc > 1) {
        num = atoi(argv[1]);
        if(num <= 0)
            num = 1;
    }

    pid = getpid();
    srand(time(NULL) * (unsigned int)pid);

    /* Not a perfect seed, but not bad */
    seed = malloc(bbs_seed_size);
    for(ix = 0; ix < bbs_seed_size; ix++) {
        seed[ix] = rand() % UCHAR_MAX;
    }

    bbs_srand(seed, bbs_seed_size);
    memset(seed, 0, bbs_seed_size);
    free(seed);

    while(num-- > 0) {
        ix = bbs_rand();

        printf("%u\n", ix);
    }

    return 0;

}
