NAME asn1_der_decoding_element - Fill the element named ELEMENTNAME of the structure STRUCTURE with values of a DER encoding string.

SYNOPSIS #include <libtasn1.h>

asn1_retCode asn1_der_decoding_element(ASN1_TYPE * structure, const char * elementName, const void * ider, int len, char * errorDescrip- tion);

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 struc- ture.

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 sructure must just be created with function 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 DER encoding OK.

ASN1_ELEMENT_NOT_FOUND ELEMENT is ASN1_TYPE_EMPTY or elementName == NULL.

ASN1_TAG_ERROR,ASN1_DER_ERROR: The der encoding doesnt match the structure STRUCTURE. *ELEMENT deleted.
