Name

asn1_der_decoding_element - API function

Synopsis

int  asn1_der_decoding_element(asn1_node * structure, const char * ele-
mentName, const void * ider, int len, char * errorDescription);

Description

libtasn1                                          asn1_der_decoding_element(3)



NAME
       asn1_der_decoding_element - API function

SYNOPSIS
       #include <libtasn1.h>

       int  asn1_der_decoding_element(asn1_node * structure, const char * ele-
       mentName, 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  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  structure  must  just be created with function asn1_cre-
       ate_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_decod-
       ing 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).
