37 | .Sh DESCRIPTION | ||
38 | These functions decode and encode the ASN.1 value NULL of type NULL. | ||
39 | For details about the semantics, examples, caveats, and bugs, see | ||
40 | .Xr ASN1_item_d2i 3 . | ||
41 | .Pp | ||
42 | .Fn d2i_ASN1_NULL | ||
43 | verifies that the BER-encoded value at | ||
44 | .Pf * Fa der_in | ||
45 | is NULL and of type NULL. | ||
46 | It fails if | ||
47 | .Fa length | ||
48 | is less than 2 or if the first two bytes of | ||
49 | .Pf * Fa der_in | ||
50 | differ from 0x05 and 0x00. | ||
51 | In case of success, | ||
52 | .Pf * Fa der_in | ||
53 | is advanced by two bytes and | ||
54 | .Pf * Fa val_out | ||
55 | is set to a specific invalid pointer representing the unique | ||
56 | .Vt ASN1_NULL | ||
57 | object. | ||
58 | .Pp | ||
59 | .Fn i2d_ASN1_NULL | ||
60 | ignores | ||
61 | .Fa val_in | ||
62 | and encodes the ASN.1 value NULL of type NULL using DER. | ||
63 | Specifically, it writes the identifier octet for the type NULL, | ||
64 | 0x05, followed by the length octet 0x00, and no content or | ||
65 | end-of-content octets. | ||
66 | .Sh RETURN VALUES | ||
67 | .Fn d2i_ASN1_NULL | ||
68 | returns a specific invalid pointer representing the unique | ||
69 | .Vt ASN1_NULL | ||
70 | object or | ||
71 | .Dv NULL | ||
72 | if an error occurs. | ||
73 | .Pp | ||
74 | .Fn i2d_ASN1_NULL | ||
75 | returns 2 if successful or 0 if an error occurs. | ||
