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 * 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 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 doesn't match the structure STRUCTURE. *ELEMENT deleted.
