glibc is providing open64 and other lfs64 functions but musl aliases them to normal equivalents since off_t is always 64-bit on musl, therefore check for target env along when target OS is linux before using open64, this is more available. Latest Musl has made these namespace changes [1] There is no need for using LFS64 open explicitly as we are only using it for opening device files and not real files [1] https://git.musl-libc.org/cgit/musl/commit/?id=246f1c811448f37a44b41cd8df8d0ef9736d95f4 Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Khem Raj <raj.khem@gmail.com>
getrandom
A Rust library for retrieving random data from (operating) system sources. It is
assumed that the system always provides high-quality cryptographically secure random
data, ideally backed by hardware entropy sources. This crate derives its name
from Linux's getrandom function, but is cross-platform, roughly supporting
the same set of platforms as Rust's std lib.
This is a low-level API. Most users should prefer using high-level random-number
library like rand.
Usage
Add this to your Cargo.toml:
[dependencies]
getrandom = "0.2"
Then invoke the getrandom function:
fn get_random_buf() -> Result<[u8; 32], getrandom::Error> {
let mut buf = [0u8; 32];
getrandom::getrandom(&mut buf)?;
Ok(buf)
}
For more information about supported targets, entropy sources, no_std targets,
crate features, WASM support and Custom RNGs see the
getrandom documentation and
getrandom::Error documentation.
Minimum Supported Rust Version
This crate requires Rust 1.36.0 or later.
