- =head1 DESCRIPTION
- ITAV is short for InfoTypeAndValue.
- OSSL_CMP_ITAV_new_caCerts() creates an B<OSSL_CMP_ITAV> structure of type
- B<caCerts> and fills it with a copy of the provided list of certificates.
- The I<caCerts> argument may be NULL or contain any number of certificates.
- OSSL_CMP_ITAV_get0_caCerts() requires that I<itav> has type B<caCerts>.
- It assigns NULL to I<*out> if there are no CA certificates in I<itav>, otherwise
- the internal pointer of type B<STACK_OF(X509)> with the certificates present.
- OSSL_CMP_ITAV_new_rootCaCert() creates a new B<OSSL_CMP_ITAV> structure
- of type B<rootCaCert> that includes the optionally given certificate.
- OSSL_CMP_ITAV_get0_rootCaCert() requires that I<itav> has type B<rootCaCert>.
- It assigns NULL to I<*out> if no certificate is included in I<itav>, otherwise
- the internal pointer to the certificate contained in the infoValue field.
- OSSL_CMP_ITAV_new_rootCaKeyUpdate() creates a new B<OSSL_CMP_ITAV> structure
- of type B<rootCaKeyUpdate> that includes an RootCaKeyUpdateContent structure
- with the optional I<newWithNew>, I<newWithOld>, and I<oldWithNew> certificates.
- OSSL_CMP_ITAV_get0_rootCaKeyUpdate() requires that I<itav> has infoType
- B<rootCaKeyUpdate>.
- If an update of a root CA certificate is included,
- it assigns to I<*newWithNew> the internal pointer
- to the certificate contained in the newWithNew infoValue sub-field of I<itav>.
- If I<newWithOld> is not NULL, it assigns to I<*newWithOld> the internal pointer
- to the certificate contained in the newWithOld infoValue sub-field of I<itav>.
- If I<oldWithNew> is not NULL, it assigns to I<*oldWithNew> the internal pointer
- to the certificate contained in the oldWithNew infoValue sub-field of I<itav>.
- Each of these pointers will be NULL if the respective sub-field is not set.
- =head1 NOTES
- CMP is defined in RFC 4210.
- =head1 RETURN VALUES
- OSSL_CMP_ITAV_new_caCerts(),
- OSSL_CMP_ITAV_new_rootCaCert(), and OSSL_CMP_ITAV_new_rootCaKeyUpdate()
- return a pointer to the new ITAV structure on success, or NULL on error.
- OSSL_CMP_ITAV_get0_caCerts(),
- OSSL_CMP_ITAV_get0_rootCaCert(), and OSSL_CMP_ITAV_get0_rootCaKeyUpdate()
- return 1 on success, 0 on error.
