DESCRIPTION
These functions decode and encode Cryptographic Message Syntax data structures. For details about the semantics, examples, caveats, and bugs, see ASN1_item_d2i(3).d2i_CMS_ContentInfo() and
i2d_CMS_ContentInfo() decode and encode a
CMS_ContentInfo structure defined in RFC 5652
section 3. d2i_CMS_bio() and
i2d_CMS_bio() are similar except that they
decode or encode using a BIO pointer.
d2i_CMS_ReceiptRequest() and
i2d_CMS_ReceiptRequest() decode and encode
a CMS_ReceiptRequest structure defined in RFC
2634 section 2.7.
RETURN VALUES
d2i_CMS_ContentInfo() and
d2i_CMS_bio() return a valid
CMS_ContentInfo structure or
NULL if an error occurs.
d2i_CMS_ReceiptRequest() returns a valid
CMS_ReceiptRequest structure or
NULL if an error occurs.
i2d_CMS_ContentInfo() and
i2d_CMS_ReceiptRequest() return the number
of bytes successfully encoded or a negative value if an error occurs.
i2d_CMS_bio() returns 1 for success or 0 if
an error occurs.
For all functions, the error code can be obtained by
ERR_get_error(3).
