Description

getentropy is an OpenBSD system call that's at the heart of the implementation of arc4random(). getentropy in designed to get contents from /dev/urandom without using a file descriptor and thus negating the potential for EMFILE or a chroot. In this case, it will be a libc wrapper around a more general interface for fetching random and psuedo-random data from the kernel.
