.Sh DESCRIPTION
.Fn CMS_ContentInfo_new
allocates and initializes an empty
.Vt CMS_ContentInfo
object, representing an ASN.1
.Vt ContentInfo
structure defined in RFC 5652 section 3.
It can hold a pointer to an ASN.1 OBJECT IDENTIFIER
and a pointer to either a
.Vt SignedData ,
.Vt EnvelopedData ,
.Vt DigestedData ,
.Vt EncryptedData ,
.Vt AuthenticatedData ,
or
.Vt CompressedData
object or to an arbitrary ASN.1 object.
.Fn CMS_ContentInfo_free
frees
.Fa cms .
.Pp
.Fn CMS_ContentInfo_print_ctx
prints a human readable representation of
.Fa cms
to
.Fa out .
.Pp
.Fn CMS_ReceiptRequest_new
allocates and initializes an empty
.Vt CMS_ReceiptRequest
object, representing an ASN.1
.Vt ReceiptRequest
structure defined in RFC 2634 section 2.7.
It can contain a content identifier, a list of recipients requested
to return a signed receipt, and a list of users to send the receipt to.
.Fn CMS_ReceiptRequest_free
frees
.Fa rr .
.Sh RETURN VALUES
.Fn CMS_ContentInfo_new
and
.Fn CMS_ReceiptRequest_new
return the new
.Vt CMS_ContentInfo
or
.Vt CMS_ReceiptRequest
object, respectively, or
.Dv NULL
if an error occurs.
