-//! Implementation for the Solaris family
-//!
-//! Read from `/dev/random`, with chunks of limited size (256 bytes).
-//! `/dev/random` uses the Hash_DRBG with SHA512 algorithm from NIST SP 800-90A.
-//! `/dev/urandom` uses the FIPS 186-2 algorithm, which is considered less
-//! secure. We choose to read from `/dev/random`.
-//!
-//! Since Solaris 11.3 and mid-2015 illumos, the `getrandom` syscall is available.
-//! To make sure we can compile on both Solaris and its derivatives, as well as
-//! function, we check for the existence of getrandom(2) in libc by calling
-//! libc::dlsym.
