NAME

       asn1_der_decoding_element - API function

SYNOPSIS

       #include <libtasn1.h>

       int  asn1_der_decoding_element(asn1_node * structure, const char * elementName, const void
       * ider, int len, char * errorDescription);

ARGUMENTS

       asn1_node * 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 structure.

       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  structure
       must just be created with function asn1_create_element().  The DER vector must contain the
       encoding string of the whole   STRUCTURE  .   If  an  error  occurs  during  the  decoding
       procedure, the * STRUCTURE is deleted and set equal to NULL.

       This  function  is  deprecated  and  may  just  be an alias to asn1_der_decoding in future
       versions. Use asn1_der_decoding() instead.

RETURNS

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