title: How to generate truly random numbers (NOT pseudo) in Linux
body: <p>What is the (best) way to create a secure random numbers in Linux (C/ C++ code), more random than the general rand() results, and not pseudo as OpenSSL BN_rand?</p>
  
  <p>In Windows I found <code>CryptGenRandom()</code> as a good option. Is there any equivalent in Linux?</p>
  
  <p>Thank you in advance.</p>
