=head1 SYNOPSIS
#include <openssl/cmp.h>
OSSL_CMP_PKIHEADER *OSSL_CMP_MSG_get0_header(const OSSL_CMP_MSG *msg);
+ OSSL_CMP_MSG *d2i_OSSL_CMP_MSG_bio(BIO *bio, OSSL_CMP_MSG **msg);
+ int i2d_OSSL_CMP_MSG_bio(BIO *bio, const OSSL_CMP_MSG *msg);
=head1 DESCRIPTION
OSSL_CMP_MSG_get0_header returns the header of the given CMP message.
+d2i_OSSL_CMP_MSG_bio parses an ASN.1-encoded OSSL_CMP_MSG from the BIO I<bio>.
+It assigns a pointer to the new structure to I<*msg> if I<msg> is not NULL.
+
+i2d_OSSL_CMP_MSG_bio writes the OSSL_CMP_MSG I<msg> in ASN.1 encoding
+to BIO I<bio>.
