NAME

6       asn1_der_decoding_element - API function
7

SYNOPSIS

9       #include <libtasn1.h>
10
11       int  asn1_der_decoding_element(asn1_node * structure, const char * ele‐
12       mentName, const void * ider, int len, char * errorDescription);
13

ARGUMENTS

15       asn1_node * structure
16                   pointer to an ASN1 structure
17
18       const char * elementName
19                   name of the element to fill
20
21       const void * ider
22                   vector that contains the DER encoding of the  whole  struc‐
23                   ture.
24
25       int len     number of bytes of *der: der[0]..der[len-1]
26
27       char * errorDescription
28                   null-terminated  string  contains  details  when  an  error
29                   occurred.

DESCRIPTION

32       Fill the element named  ELEMENTNAME  with  values  of  a  DER  encoding
33       string.   The  structure  must  just be created with function asn1_cre‐
34       ate_element().  The DER vector must contain the encoding string of  the
35       whole   STRUCTURE  .  If an error occurs during the decoding procedure,
36       the * STRUCTURE is deleted and set equal to NULL.
37
38       This function is deprecated and may just be an alias to asn1_der_decod‐
39       ing in future versions. Use asn1_der_decoding() instead.

RETURNS

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