CMS_ContentInfo *
CMS_ContentInfo_new(void);
void
CMS_ContentInfo_free(CMS_ContentInfo
*cms);

CMS_ContentInfo_print_ctx(BIO
*out, CMS_ContentInfo *cms, int
indent, const ASN1_PCTX *pctx);

*rr);
DESCRIPTION
CMS_ContentInfo_new()
allocates and initializes an empty CMS_ContentInfo
object, representing an ASN.1 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 SignedData,
EnvelopedData, DigestedData,
EncryptedData, AuthenticatedData,
or CompressedData object or to an arbitrary ASN.1
object.
CMS_ContentInfo_free()
frees cms.
CMS_ContentInfo_print_ctx()
prints a human readable representation of cms to
out.
CMS_ReceiptRequest_new()
allocates and initializes an empty CMS_ReceiptRequest
object, representing an ASN.1 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.
CMS_ReceiptRequest_free()
frees rr.
RETURN VALUES
CMS_ContentInfo_new() and
CMS_ReceiptRequest_new() return the new
CMS_ContentInfo or
CMS_ReceiptRequest object, respectively, or
NULL if an error occurs.
