asn1_der_decoding_startEnd(3)	   libtasn1	 asn1_der_decoding_startEnd(3)

NAME
       asn1_der_decoding_startEnd - Find the start and end point of an element
       in a DER encoding string.

SYNOPSIS
       #include <libtasn1.h>

       asn1_retCode asn1_der_decoding_startEnd(ASN1_TYPE element, const void *
       ider, int len, const char * name_element, int * start, int * end);

ARGUMENTS
       ASN1_TYPE 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.

EXAMPLE
       the sequence "tbsCertificate" inside an X509 certificate.

RETURNS
ASN1_SUCCESS
       DER encoding OK.

ASN1_ELEMENT_NOT_FOUND
       ELEMENT is ASN1_TYPE EMPTY or NAME_ELEMENT is not a valid element.

       ASN1_TAG_ERROR,ASN1_DER_ERROR:  the  der	 encoding  doesn't  match  the
       structure ELEMENT.
