asn1_der_decoding_startEnd(3)	   libtasn1	 asn1_der_decoding_startEnd(3)

NAME
       asn1_der_decoding_startEnd - API function

SYNOPSIS
       #include <libtasn1.h>

       int  asn1_der_decoding_startEnd(asn1_node  element,  const void * ider,
       int 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 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  certifi‐
       cate.

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 ELE‐
       MENT.
