/dev/urandom vs. /dev/random

<OT>
A system call generally works by invoking code within the OS kernel
rather than in a user-mode library. On a Unix-like system, system
calls are documented by man pages in section 2, library functions in
section 3.

Occasionally confused with the standard library function called "system".

system() is typically implemented as a library function, not as a
system call.
