asn1_der_decoding_element - API function
int asn1_der_decoding_element(asn1_node * structure, const char * ele-
mentName, const void * ider, int len, char * errorDescription);
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 struc-
int len number of bytes of *der: der..der[len-1]
char * errorDescription
null-terminated string contains details when an error
Fill the element named ELEMENTNAME with values of a DER encoding
string. The structure must just be created with function asn1_cre-
ate_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_decod-
ing in future versions. Use asn1_der_decoding() instead.
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
