Function getrandom

pub fn getrandom(buf: &mut [u8], flags: GetRandomFlags) -> Result<usize, Errno> 

Available on crate feature dep_rustix only.

getrandom(buf, flags)—Reads a sequence of random bytes.

This is a very low-level API which may be difficult to use correctly. Most users should prefer to use getrandom or rand APIs instead.

This takes a &mut [u8] which Rust requires to contain initialized memory. To use an uninitialized buffer, use getrandom_uninit.
