@deftypefun {int} {asn1_der_coding} (asn1_node @var{element}, const char * @var{name}, void * @var{ider}, int * @var{len}, char * @var{ErrorDescription})
@var{element}: pointer to an ASN1 element
@var{name}: the name of the structure you want to encode (it must be
inside *POINTER).
@var{ider}: vector that will contain the DER encoding. DER must be a
pointer to memory cells already allocated.
@var{len}: number of bytes of * @code{ider} : @code{ider} [0].. @code{ider} [len-1], Initialy
holds the sizeof of der vector.
@var{ErrorDescription}: return the error description or an empty
string if success.
Creates the DER encoding for the NAME structure (inside *POINTER
structure).
@strong{Returns:} @code{ASN1_SUCCESS} if DER encoding OK, @code{ASN1_ELEMENT_NOT_FOUND}
if @code{name} is not a valid element, @code{ASN1_VALUE_NOT_FOUND} if there
is an element without a value, @code{ASN1_MEM_ERROR} if the @code{ider} vector isn't big enough and in this case @code{len} will contain the
length needed.
