NAME

6       asn1_der_decoding - API function
7

SYNOPSIS

9       #include <libtasn1.h>
10
11       asn1_retCode  asn1_der_decoding(ASN1_TYPE * element, const void * ider,
12       int len, char * errorDescription);
13

ARGUMENTS

15       ASN1_TYPE * element
16                   pointer to an ASN1 structure.
17
18       const void * ider
19                   vector that contains the DER encoding.
20
21       int len     number of bytes of *ider: ider[0]..ider[len-1].
22
23       char * errorDescription
24                   null-terminated  string  contains  details  when  an  error
25                   occurred.
26

DESCRIPTION

28       Fill  the  structure *ELEMENT with values of a DER encoding string. The
29       structure must just be created with function asn1_create_element().  If
30       an  error occurs during the decoding procedure, the *ELEMENT is deleted
31       and set equal to ASN1_TYPE_EMPTY.
32

RETURNS

34       ASN1_SUCCESS if DER encoding OK, ASN1_ELEMENT_NOT_FOUND if  ELEMENT  is
35       ASN1_TYPE_EMPTY, and ASN1_TAG_ERROR or ASN1_DER_ERROR if the der encod‐
36       ing doesn't match the structure name (*ELEMENT deleted).
