11 int asn1_der_coding(asn1_node element, const char * name, void * ider,
12 int * len, char * ErrorDescription);
13
15 asn1_node element
16 pointer to an ASN1 element
17
18 const char * name
19 the name of the structure you want to encode (it must be
20 inside *POINTER).
21
22 void * ider vector that will contain the DER encoding. DER must be a
23 pointer to memory cells already allocated.
24
25 int * len number of bytes of * ider : ider [0].. ider [len-1], Ini‐
26 tialy holds the sizeof of der vector.
27
28 char * ErrorDescription
29 return the error description or an empty string if success.
30
32 Creates the DER encoding for the NAME structure (inside *POINTER struc‐
33 ture).
34
36 ASN1_SUCCESS if DER encoding OK, ASN1_ELEMENT_NOT_FOUND if name is not
37 a valid element, ASN1_VALUE_NOT_FOUND if there is an element without a
38 value, ASN1_MEM_ERROR if the ider vector isn't big enough and in this
39 case len will contain the length needed.
