to NULL. Otherwise they are set to pointers to their respective values. These
point directly to the internal representations of the values and therefore
should not be freed directly.
+Any of the out parameters B<p>, B<q>, and B<g> can be NULL, in which case no
+value will be returned for that parameter.
The B<p>, B<q> and B<g> values can be set by calling DH_set0_pqg() and passing
the new values for B<p>, B<q> and B<g> as parameters to the function. Calling
been set yet, although if the private key has been set then the public key must
be. The values point to the internal representation of the public key and
private key values. This memory should not be freed directly.
+Any of the out parameters B<pub_key> and B<priv_key> can be NULL, in which case
+no value will be returned for that parameter.
The public and private key values can be set using DH_set0_key(). Either
parameter may be NULL, which means the corresponding DH field is left
DH_set0_pqg() and DH_set0_key() return 1 on success or 0 on failure.
DH_get0_p(), DH_get0_q(), DH_get0_g(), DH_get0_priv_key(), and DH_get0_pub_key()
-return the respective value.
+return the respective value, or NULL if it is unset.
DH_test_flags() returns the current state of the flags in the DH object.
