NAME
asn1_der_decoding_element - API function
SYNOPSIS
#include <libtasn1.h> int asn1_der_decoding_element(asn1_node * structure, const char * elementName, 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
structure.
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_create_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_decoding 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).
