Would you please say more.  The man page says:

       RAND_bytes() puts num cryptographically strong pseudo-random bytes into
       buf. An error occurs if the PRNG has not been seeded with enough
       randomness to ensure an unpredictable byte sequence.

How can I be sure that it has "been seeded with enough"?
