GetRandom functionv0.1.0

pub func GetRandom(
    buffer: *var opaque,
    length: uint
) -> bool

buffer is borrowed and written; length is read by value. Returns true when the whole buffer was filled, and false when the provider refused — there is no partial success to handle, unlike every Unix source. Runs in time proportional to length and allocates nothing. buffer must be writable for length bytes. length is passed as a 32-bit count, so a request above four gigabytes is refused rather than truncated.

Parameters

Returns: whether the whole buffer was filled; there is no partial success

BCRYPT_USE_SYSTEM_PREFERRED_RNG: draw from the system's preferred generator rather than a named algorithm. Passed with a null algorithm handle, which is what makes this a one-call interface: nothing has to be opened, configured, or closed.
