RAND_egd_bytes() queries the entropy gathering daemon EGD on socket B<path>.
It queries B<bytes> bytes and uses L<RAND_add(3)|RAND_add(3)> to seed the
OpenSSL built-in PRNG.
+This function is more flexible than RAND_egd().
+When only one secret key must
+be generated, it is not necessary to request the full amount 255 bytes from
+the EGD socket. This can be advantageous, since the amount of entropy
+that can be retrieved from EGD over time is limited.
RAND_query_egd_bytes() performs the actual query of the EGD daemon on socket
B<path>. If B<buf> is given, B<bytes> bytes are queried and written into
a socket interface through which entropy can be gathered in chunks up to
255 bytes. Several chunks can be queried during one connection.
-While RAND_egd() is longer available (see HISTORY section), the
-RAND_egd_bytes() function is more flexible. When only one secret key must
-be generated, it is not needed to request the full amount 255 bytes from
-the EGD socket. This can be advantageous, since the amount of entropy
-that can be retrieved from EGD over time is limited.

EGD is available from http://www.lothar.com/tech/crypto/ (C<perl
Makefile.PL; make; make install> to install). It is run as B<egd>
I<path>, where I<path> is an absolute path designating a socket. When
