NAME
       asn1_der_decoding - API function

SYNOPSIS
       #include <libtasn1.h>

       asn1_retCode asn1_der_decoding(ASN1_TYPE * element, const void * ider, int len, char * errorDescription);

ARGUMENTS
       ASN1_TYPE * element
		   pointer to an ASN1 structure.

       const void * ider
		   vector that contains the DER encoding.

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

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

DESCRIPTION
       Fill  the  structure *ELEMENT with values of a DER encoding string. The structure must just be created with function asn1_create_element().
       If an error occurs during the decoding procedure, the *ELEMENT is deleted and set equal to ASN1_TYPE_EMPTY.

RETURNS
       ASN1_SUCCESS if DER encoding OK, ASN1_ELEMENT_NOT_FOUND if ELEMENT is ASN1_TYPE_EMPTY, and ASN1_TAG_ERROR  or  ASN1_DER_ERROR  if  the  der
       encoding doesn't match the structure name (*ELEMENT deleted).
