NAME
       asn1_der_decoding_element  -  Fill the element named ELEMENTNAME of the
       structure STRUCTURE with values of a DER encoding string.

SYNOPSIS
       #include <libtasn1.h>

       asn1_retCode  asn1_der_decoding_element(ASN1_TYPE  *  structure,  const
       char  *  elementName,  const void * ider, int len, char * errorDescrip-
       tion);

ARGUMENTS
       ASN1_TYPE * structure
                   pointer to an ASN1 structure

       const char * elementName
                   name of the element to fill

       const void * ider
                   vector that contains the DER encoding of the  whole  struc-
                   ture.

       int len     number of bytes of *der: der[0]..der[len-1]

       char * errorDescription
                   null-terminated  string  contains  details  when  an  error
                   occurred.

DESCRIPTION
       Fill the element named  ELEMENTNAME  with  values  of  a  DER  encoding
       string.   The sructure must just be created with function string of the
       whole STRUCTURE.  If an error occurs during the decoding procedure, the
       *STRUCTURE is deleted and set equal to ASN1_TYPE_EMPTY.

RETURNS
ASN1_SUCCESS
       DER encoding OK.

ASN1_ELEMENT_NOT_FOUND
       ELEMENT is ASN1_TYPE_EMPTY or elementName == NULL.

       ASN1_TAG_ERROR,ASN1_DER_ERROR:  The  der  encoding  doesn't  match  the
       structure STRUCTURE. *ELEMENT deleted.
