Generate random data via the internal PRNG.
Synopsis
Declared in <random.h>
void
GetRandBytes(std::span<unsigned char> bytes) noexcept;Description
These functions are designed to be fast (sub microsecond), but do not necessarily meaningfully add entropy to the PRNG state.
In test mode (see SeedRandomForTest in src/test/util/random.h), the normal PRNG state is bypassed, and a deterministic, seeded, PRNG is used instead.
Thread‐safe.
