.SH NAME
asn1_der_coding \- API function
.SH SYNOPSIS
.B #include <libtasn1.h>
.sp
.BI "int asn1_der_coding(asn1_node_const " element ", const char * " name ", void * " ider ", int * " len ", char * " ErrorDescription ");"
.SH ARGUMENTS
.IP "asn1_node_const element" 12
pointer to an ASN1 element
.IP "const char * name" 12
the name of the structure you want to encode (it must be
inside *POINTER).
.IP "void * ider" 12
vector that will contain the DER encoding. DER must be a
pointer to memory cells already allocated.
.IP "int * len" 12
number of bytes of * \fIider\fP :  \fIider\fP [0].. \fIider\fP [len\-1], Initialy
holds the sizeof of der vector.
.IP "char * ErrorDescription" 12
return the error description or an empty
string if success.
.SH "DESCRIPTION"
Creates the DER encoding for the NAME structure (inside *POINTER
structure).
.SH "RETURNS"
\fBASN1_SUCCESS\fP if DER encoding OK, \fBASN1_ELEMENT_NOT_FOUND\fP
if  \fIname\fP is not a valid element, \fBASN1_VALUE_NOT_FOUND\fP if there
is an element without a value, \fBASN1_MEM_ERROR\fP if the  \fIider\fP vector isn't big enough and in this case  \fIlen\fP will contain the
length needed.
