20=head1 DESCRIPTION
21
22CMS_add0_cert() and CMS_add1_cert() add certificate B<cert> to B<cms>.
23must be of type signed data or enveloped data.
24
25CMS_get1_certs() returns all certificates in B<cms>.
26
27CMS_add0_crl() and CMS_add1_crl() add CRL B<crl> to B<cms>. CMS_get1_crls()
28returns any CRLs in B<cms>.
29
30=head1 NOTES
31
32The CMS_ContentInfo structure B<cms> must be of type signed data or enveloped
33data or an error will be returned.
34
35For signed data certificates and CRLs are added to the B<certificates> and
36B<crls> fields of SignedData structure. For enveloped data they are added to
37B<OriginatorInfo>.
38
39As the B<0> implies CMS_add0_cert() adds B<cert> internally to B<cms> and it
40must not be freed up after the call as opposed to CMS_add1_cert() where B<cert>
41must be freed up.
42
43The same certificate or CRL must not be added to the same cms structure more
44than once.
45
46=head1 RETURN VALUES
47
48CMS_add0_cert(), CMS_add1_cert() and CMS_add0_crl() and CMS_add1_crl() return
491 for success and 0 for failure.
50
51CMS_get1_certs() and CMS_get1_crls() return the STACK of certificates or CRLs
52or NULL if there are none or an error occurs. The only error which will occur
53in practice is if the B<cms> type is invalid.
