Otherwise, you can use the random devices as if they were files. You read from them and you get random data. I'm using open / read here, but fopen / fread would work just as well.
WebThe getrandom () system call fills the buffer pointed to by buf with up to buflen random bytes. These bytes can be used to seed user-space random number generators or for cryptographic purposes. By default, getrandom () draws entropy from the urandom source (i.e., the same source as the /dev/urandom device).
