=head1 DESCRIPTION

ossl_cmp_bodytype_to_string() returns the name of the given body type as string,
or "illegal body type" on error.

ossl_cmp_msg_get_bodytype() returns the body type of the given PKIMessage,
or -1 on error.

ossl_cmp_msg_set_bodytype() sets the type of the message contained in
the PKIMessage body field.
Returns 1 on success, 0 on error.

ossl_cmp_msg_create() creates and initializes an B<OSSL_CMP_MSG> structure,
using fields of B<ctx> for the header and B<bodytype> for the body.
If the current B<transactionID> field in I<ctx> indicates that there is no
current transaction, it creates and stores a random one with 128 bits length.
Thus, the I<ctx> may be modified by this and related ossl_cmp_*_new() functions.
Returns pointer to created B<OSSL_CMP_MSG> on success, NULL on error.

ossl_cmp_msg_gen_ITAV_push0() pushes the B<itav> to the body of the
PKIMessage B<msg> of GenMsg or GenRep type. Consumes the B<itavs> pointer.
Returns 1 on success, 0 on error.

ossl_cmp_msg_gen_ITAVs_push1() adds a copy of the B<itavs> stack to the body
of the PKIMessage B<msg> of GenMsg or GenRep type.
Does not consume the B<itavs> pointer nor its elements.
Returns 1 on success, 0 on error.

=head1 NOTES

CMP is defined in RFC 4210 (and CRMF in RFC 4211).

=head1 RETURN VALUES

See the individual functions above.
