asn1_der_coding - API function

#include <libtasn1.h>

int asn1_der_coding(asn1_node_const */element/, const char * name, void * ider, int * len, char * ErrorDescription);*

asn1_node_const element

pointer to an ASN1 element

const char * name

the name of the structure you want to encode (it must be inside *POINTER).

void * ider

vector that will contain the DER encoding. DER must be a pointer to memory cells already allocated.

int * len

number of bytes of * ider : ider [0].. ider [len-1], Initialy holds the sizeof of der vector.

char * ErrorDescription

return the error description or an empty string if success.

Creates the DER encoding for the NAME structure (inside *POINTER structure).

ASN1_SUCCESS if DER encoding OK, ASN1_ELEMENT_NOT_FOUND if name is not a valid element, ASN1_VALUE_NOT_FOUND if there is an element without a value, ASN1_MEM_ERROR if the ider vector isn’t big enough and in this case len will contain the length needed.
