size_t rb_random_interface_t::default_seed_bits |
rb_random_get_bytes_func* rb_random_interface_t::get_bytes |
Function to obtain a series of random bytes.
If your PRNG have a native method to yield arbitrary number of bytes use that to implement this. But in case you lack such things, you can do so by using rb_rand_bytes_int32()
rb_random_get_int32_func* rb_random_interface_t::get_int32 |
rb_random_get_real_func* rb_random_interface_t::get_real |
Function to obtain a random double.
If your PRNG have a native method to yield a floating point random number use that to implement this. But in case you lack such things, you can do so by using rb_int_pair_to_real().
