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