NAME

asn1_der_coding - API function

SYNOPSIS

#include <libtasn1.h>

int asn1_der_coding(asn1_node_const element, const char * name, void
* ider, int * len, char * ErrorDescription);

ARGUMENTS

asn1_node_const element
pointer to an ASN1 element

const char * name
the name of the structure you want to encode (it must be
inside *POINTER).

void * ider vector that will contain the DER encoding. DER must be a
pointer to memory cells already allocated.

int * len number of bytes of * ider : ider [0].. ider [len-1],
Initialy holds the sizeof of der vector.

char * ErrorDescription
return the error description or an empty string if
success.

DESCRIPTION

Creates the DER encoding for the NAME structure (inside *POINTER
structure).

RETURNS

ASN1_SUCCESS if DER encoding OK, ASN1_ELEMENT_NOT_FOUND if name is
not a valid element, ASN1_VALUE_NOT_FOUND if there is an element
without a value, ASN1_MEM_ERROR if the ider vector isn't big enough
and in this case len will contain the length needed.
