C++ (Cpp) lcg_calculate_constants Examples

Example #1

File: rand-lcg.c Project: 0817/masscan

int
randlcg_selftest()
{
    unsigned i;
    int is_success = 0;
    uint64_t m, a, c;


    m = 3015 * 3;

    for (i=0; i<5; i++) {
        a = 0;
        c = 0;

        m += 10 + i;

        lcg_calculate_constants(m, &a, &c, 0);

        is_success = lcg_verify(a, c, m, m);

        if (!is_success) {
            fprintf(stderr, "LCG: randomization failed\n");
            return 1; /*fail*/
        }
    }

    return 0; /*success*/
}
