These functions pass a library content and prop query.
The i2d documentation related to these functions has been corrected since the bio and fp functions always return 0 or 1.

similar to d2i_PUBKEY() and i2d_PUBKEY() except they decode or encode using a
B<BIO> or B<FILE> pointer.
+d2i_PUBKEY_ex_bio() and d2i_PUBKEY_ex_fp() are similar to d2i_PUBKEY_ex() except
+they decode using a B<BIO> or B<FILE> pointer.

X509_PUBKEY_set0_public_key() sets the public-key encoding of I<pub>
to the I<penclen> bytes contained in buffer I<penc>.
Any earlier public-key encoding in I<pub> is freed.
X509_PUBKEY_free() does not return a value.
-X509_PUBKEY_get0() and X509_PUBKEY_get() return a pointer to an B<EVP_PKEY>
-structure or NULL if an error occurs.
+X509_PUBKEY_get0(), X509_PUBKEY_get(), d2i_PUBKEY_ex(), d2i_PUBKEY(),
+d2i_PUBKEY_ex_bio(), d2i_PUBKEY_bio(), d2i_PUBKEY_ex_fp() and d2i_PUBKEY_fp()
+return a pointer to an B<EVP_PKEY> structure or NULL if an error occurs.
+
+i2d_PUBKEY() returns the number of bytes successfully encoded or a
+negative value if an error occurs.
+
+i2d_PUBKEY_fp() and i2d_PUBKEY_bio() return 1 if successfully
+encoded or 0 if an error occurs.
X509_PUBKEY_set0_public_key() does not return a value.
