NAME
       asn1_der_decoding_element - API function

SYNOPSIS
       #include <libtasn1.h>

       int  asn1_der_decoding_element(asn1_node * structure, const char * ele‐
       mentName, const void * ider, int len, char * errorDescription);

ARGUMENTS
       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‐
		   ture.

       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  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.

RETURNS
       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
       deleted).
