NAME
asn1_der_decoding_element - API function
SYNOPSIS
#include <libtasn1.h>
asn1_retCode asn1_der_decoding_element(ASN1_TYPE * structure, const
char * elementName, const void * ider, int len, char *
errorDescription);
ARGUMENTS
ASN1_TYPE * 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 ASN1_TYPE_EMPTY.
RETURNS
ASN1_SUCCESS if DER encoding OK, ASN1_ELEMENT_NOT_FOUND if ELEMENT is
ASN1_TYPE_EMPTY or elementName == NULL, and ASN1_TAG_ERROR or
ASN1_DER_ERROR if the der encoding doesn’t match the structure
structure (*ELEMENT deleted).
