 just use L<RAND_bytes(3)> to obtain random data.
 Having said that, there is one important rule to obey: Always check the error
 return value of L<RAND_bytes(3)> and do not take randomness for granted.
+Although (re-)seeding is automatic, it can fail because no trusted random source
+is available or the trusted source(s) temporarily fail to provide sufficient
+random seed material.
+In this case the CSPRNG enters an error state and ceases to provide output,
+until it is able to recover from the error by reseeding itself.
+For more details on reseeding and error recovery, see L<RAND_DRBG(7)>.

 For values that should remain secret, you can use L<RAND_priv_bytes(3)>
 instead.
