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).
