NAME

6       asn1_der_decoding_element - API function
7

SYNOPSIS

9       #include <libtasn1.h>
10
11       asn1_retCode  asn1_der_decoding_element(ASN1_TYPE  *  structure,  const
12       char * elementName, const void * ider, int len,  char  *  errorDescrip‐
13       tion);
14

ARGUMENTS

16       ASN1_TYPE * structure
17                   pointer to an ASN1 structure
18
19       const char * elementName
20                   name of the element to fill
21
22       const void * ider
23                   vector  that  contains the DER encoding of the whole struc‐
24                   ture.
25
26       int len     number of bytes of *der: der[0]..der[len-1]
27
28       char * errorDescription
29                   null-terminated  string  contains  details  when  an  error
30                   occurred.
31

DESCRIPTION

33       Fill  the  element  named  ELEMENTNAME  with  values  of a DER encoding
34       string.  The structure must just be  created  with  function  asn1_cre‐
35       ate_element().   The DER vector must contain the encoding string of the
36       whole STRUCTURE.  If an error occurs during the decoding procedure, the
37       *STRUCTURE is deleted and set equal to ASN1_TYPE_EMPTY.
38

RETURNS

40       ASN1_SUCCESS  if  DER encoding OK, ASN1_ELEMENT_NOT_FOUND if ELEMENT is
41       ASN1_TYPE_EMPTY  or  elementName  ==  NULL,   and   ASN1_TAG_ERROR   or
42       ASN1_DER_ERROR  if  the der encoding doesn't match the structure struc‐
43       ture (*ELEMENT deleted).
