-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.
 
-d2i_OSSL_CMP_MSG_bio parses an ASN.1-encoded OSSL_CMP_MSG from the BIO I<bio>.
+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).

 It assigns a pointer to the new structure to I<*msg> if I<msg> is not NULL.
