asn1_der_decoding - API function
#include <libtasn1.h>
int asn1_der_decoding(asn1_node * element, const void * ider, int
ider_len, char * errorDescription);
asn1_node * element
pointer to an ASN1 structure.
const void * ider
vector that contains the DER encoding.
int ider_len
number of bytes of * ider : ider [0].. ider [len-1].
char * errorDescription
null-terminated string contains details when an error
occurred.
Fill the structure * element with values of a DER encoding string.
The structure must just be created with function
asn1_create_element().
Note that the * element variable is provided as a pointer for
historical reasons.
ASN1_SUCCESS if DER encoding OK, ASN1_ELEMENT_NOT_FOUND if ELEMENT
is NULL, and ASN1_TAG_ERROR or ASN1_DER_ERROR if the der encoding
doesn't match the structure name (* ELEMENT deleted).
