NAMEasn1_der_decoding_startEnd - API function
- 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 .. 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

DESCRIPTIONFind 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.
RETURNSASN1_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.
