CMS_add0_cert() and CMS_add1_cert() add certificate I<cert> to I<cms>
unless it is already present.
-This is used by L<CMS_sign_ex()> and L<CMS_sign()> and may be used before
-calling L<CMS_verify()> to help chain building in certificate validation.
+This is used by L<CMS_sign_ex(3)> and L<CMS_sign(3)> and may be used before
+calling L<CMS_verify(3)> to help chain building in certificate validation.
As the 0 implies, CMS_add0_cert() adds I<cert> internally to I<cms>
and on success it must not be freed up by the caller.
In contrast, the caller of CMS_add1_cert() must free I<cert>.
CMS_add0_crl() and CMS_add1_crl() add CRL I<crl> to I<cms>.
I<cms> must be of type signed data or (authenticated) enveloped data.
For signed data, such a CRL may be used in certificate validation
-with L<CMS_verify()>.
+with L<CMS_verify(3)>.
It may be given both for inclusion when signing a CMS message
and when verifying a signed CMS message.
