RAND_seed() is equivalent to RAND_add() with B<randomness> set to B<num>.
+RAND_keep_random_devices_open() is used to control file descriptor
+usage by the random seed sources. Some seed sources maintain open file
+descriptors by default, which allows such sources to operate in a
+chroot(2) jail without the associated device nodes being available. When
+the B<keep> argument is zero, this call disables the retention of file
+descriptors. Conversely, a non-zero argument enables the retention of
+file descriptors. This function is usually called during initialization
+and it takes effect immediately.

RAND_event() and RAND_screen() are equivalent to RAND_poll() and exist
for compatibility reasons only. See HISTORY section below.
