asn1_der_coding(3)                 libtasn1                 asn1_der_coding(3)


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.
