+=head1 NAME
+
+ CMS_add0_cert, CMS_add1_cert, CMS_get1_certs, CMS_add0_crl, CMS_get1_crls, - CMS certificate and CRL utility functions
+
+=head1 SYNOPSIS
+
+ #include <openssl/cms.h>
+
+ int CMS_add0_cert(CMS_ContentInfo *cms, X509 *cert);
+ int CMS_add1_cert(CMS_ContentInfo *cms, X509 *cert);
+ STACK_OF(X509) *CMS_get1_certs(CMS_ContentInfo *cms);
+
+ int CMS_add0_crl(CMS_ContentInfo *cms, X509_CRL *crl);
+ STACK_OF(X509_CRL) *CMS_get1_crls(CMS_ContentInfo *cms);
+
+
+=head1 DESCRIPTION
+
+CMS_add0_cert() and CMS_add1_cert() add certificate B<cert> to B<cms> which
+must be of type signed data or enveloped data. 
+
+CMS_get1_certs() returns all certificates in B<cms>.
+
+CMS_add0_crl() adds CRL B<crl> to B<cms> which must be of type signed data or
+enveloped data. CMS_get1_crls() returns any CRLs in B<cms>.
+
+=head1 NOTES
+
+As the B<0> implies CMS_add0_cert() adds B<cert> internally to B<cms> and it
+must not be freed up after the call as opposed to CMS_add1_cert() where B<cert>
+must be freed up.
+
+The same certificate or CRL must not be added to the same cms structure more
+than once.
+
+For signed data CMS types certificates and CRLs are added to the
+B<certificates> and B<crls> fields of the SignedData structure. For enveloped
+data they are added to B<OriginatorInfo>.
+
+=head1 RETURN VALUES
+
+CMS_add0_cert(), CMS_add1_cert() and CMS_add0_crl() return 1 for success and
+0 for failure. 
+
+CMS_get1_certs() and CMS_get1_crls() return the STACK of certificates or CRLs
+or NULL if there are none or an error occurs. The only error which will occur
+in practice is if the B<cms> type is invalid.

+
+CMS_get0_type(), CMS_set1_eContentType() and CMS_get0_eContentType() were all
+first added to OpenSSL 0.9.8
