=head1 DESCRIPTION

Each of the OSSL_CRMF_MSG_get0_regCtrl_X() functions
returns the respective control X in the given I<msg>, if present.

OSSL_CRMF_MSG_set1_regCtrl_regToken() sets the regToken control in the given
I<msg> copying the given I<tok> as value. See RFC 4211, section 6.1.

OSSL_CRMF_MSG_set1_regCtrl_authenticator() sets the authenticator control in
the given I<msg> copying the given I<auth> as value. See RFC 4211, section 6.2.

OSSL_CRMF_MSG_PKIPublicationInfo_push0_SinglePubInfo() pushes the given I<spi>
to I<si>. Consumes the I<spi> pointer.

OSSL_CRMF_MSG_set0_SinglePubInfo() sets in the given SinglePubInfo I<spi>
the I<method> and publication location, in the form of a GeneralName, I<nm>.
The publication location is optional, and therefore I<nm> may be NULL.
The function consumes the I<nm> pointer if present.
Available methods are:
 # define OSSL_CRMF_PUB_METHOD_DONTCARE 0
 # define OSSL_CRMF_PUB_METHOD_X500     1
 # define OSSL_CRMF_PUB_METHOD_WEB      2
 # define OSSL_CRMF_PUB_METHOD_LDAP     3

OSSL_CRMF_MSG_set_PKIPublicationInfo_action() sets the action in the given I<pi>
using the given I<action> as value. See RFC 4211, section 6.3.
Available actions are:
 # define OSSL_CRMF_PUB_ACTION_DONTPUBLISH   0
 # define OSSL_CRMF_PUB_ACTION_PLEASEPUBLISH 1

OSSL_CRMF_MSG_set1_regCtrl_pkiPublicationInfo() sets the pkiPublicationInfo
control in the given I<msg> copying the given I<tok> as value. See RFC 4211,
section 6.3.

OSSL_CRMF_MSG_set1_regCtrl_protocolEncrKey() sets the protocolEncrKey control in
the given I<msg> copying the given I<pubkey> as value. See RFC 4211 section 6.6.

OSSL_CRMF_MSG_set1_regCtrl_oldCertID() sets the oldCertID control in the given
I<msg> copying the given I<cid> as value. See RFC 4211, section 6.5.

OSSL_CRMF_CERTID_gen produces an OSSL_CRMF_CERTID_gen structure copying the
given I<issuer> name and I<serial> number.

=head1 RETURN VALUES

All OSSL_CRMF_MSG_get0_*() functions
return the respective pointer value or NULL if not present and on error.

All OSSL_CRMF_MSG_set1_*() functions return 1 on success, 0 on error.

OSSL_CRMF_CERTID_gen() returns a pointer to the resulting structure
or NULL on error.

=head1 NOTES

A function OSSL_CRMF_MSG_set1_regCtrl_pkiArchiveOptions() for setting an
Archive Options Control is not yet implemented due to missing features to
create the needed OSSL_CRMF_PKIARCHIVEOPTINS content.
