       asn1_der_decoding2 - API function


       #include <libtasn1.h>

       int  asn1_der_decoding2(asn1_node  *  element,  const  void  *  ider,  int * max_ider_len,
       unsigned int flags, char * errorDescription);


       asn1_node * element
                   pointer to an ASN1 structure.

       const void * ider
                   vector that contains the DER encoding.

       int * max_ider_len
                   pointer to an integer giving the information about the maximal number of bytes
                   occupied  by  *  ider  . The real size of the DER encoding is returned through
                   this pointer.

       unsigned int flags
                   flags controlling the behaviour of the function.

       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().

       If  ASN1_DECODE_FLAG_ALLOW_PADDING flag is set then the function will ignore padding after
       the decoded DER data. Upon a successful return the value of * max_ider_len will be set  to
       the number of bytes decoded.

       If  ASN1_DECODE_FLAG_STRICT_DER  flag  is  set  then  the  function  will  not  decode any
       BER-encoded elements.


       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).
