- function(s) manipulating CMP messages
=head1 SYNOPSIS
#include <openssl/cmp.h>
OSSL_CMP_PKIHEADER *OSSL_CMP_MSG_get0_header(const OSSL_CMP_MSG *msg);
+ int OSSL_CMP_MSG_update_transactionID(OSSL_CMP_CTX *ctx, 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.
+OSSL_CMP_MSG_get0_header() returns the header of the given CMP message.
+
+OSSL_CMP_MSG_update_transactionID() updates the transactionID field
+in the header of the given message according to the CMP_CTX.
+This requires re-protecting the message (if it was protected).
+
+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>.
=head1 NOTES
=head1 RETURN VALUES
-CMP_MSG_get0_header() returns the intended pointer value as described above
+OSSL_CMP_MSG_get0_header() returns the intended pointer value as described above
or NULL if the respective entry does not exist and on error.
+d2i_OSSL_CMP_MSG_bio() returns the parsed message or NULL on error.
+
+i2d_OSSL_CMP_MSG_bio() and OSSL_CMP_MSG_update_transactionID()
+return 1 on success, 0 on error.
