 BN_rand() generates a cryptographically strong pseudo-random number of
 B<bits> in length and stores it in B<rnd>.
-The value of B<bits> must be zero or greater.
+If B<bits> is less than zero, or too small to
+accomodate the requirements specified by the B<top> and B<bottom>
+parameters, an error is returned.
 The B<top> parameters specifies
 requirements on the most significant bit of the generated number.
 If it is B<BN_RAND_TOP_ANY>, there is no constraint.
