NAME

       asn1_der_decoding_startEnd - API function

SYNOPSIS

       #include <libtasn1.h>

       int  asn1_der_decoding_startEnd(asn1_node  element, const void * ider, int ider_len, const
       char * name_element, int * start, int * end);

ARGUMENTS

       asn1_node element
                   pointer to an ASN1 element

       const void * ider
                   vector that contains the DER encoding.

       int ider_len
                   number of bytes of * ider :  ider [0].. ider [len-1]

       const char * name_element
                   an element of NAME structure.

       int * start the position of the first byte of NAME_ELEMENT decoding ( ider [*start])

       int * end   the position of the last byte of NAME_ELEMENT decoding ( ider [*end])

DESCRIPTION

       Find the start and end point of an element in a DER encoding string. I mean  that  if  you
       have  a  der encoding and you have already used the function asn1_der_decoding() to fill a
       structure, it may happen that you want to find the piece of string concerning  an  element
       of the structure.

       One example is the sequence "tbsCertificate" inside an X509 certificate.

       Note  that  since  libtasn1  3.7 the  ider and  ider_len parameters can be omitted, if the
       element is already decoded using asn1_der_decoding().

RETURNS

       ASN1_SUCCESS if DER encoding OK, ASN1_ELEMENT_NOT_FOUND if ELEMENT is asn1_node  EMPTY  or
       name_element  is not a valid element, ASN1_TAG_ERROR or ASN1_DER_ERROR if the der encoding
       doesn't match the structure ELEMENT.
