SYNOPSIS
       #include <gnutls/x509.h>

       int gnutls_x509_crt_get_extension_oid(gnutls_x509_crt_t cert, int indx, void * oid, size_t * oid_size);

ARGUMENTS
       gnutls_x509_crt_t cert
		   should contain a gnutls_x509_crt_t structure

       int indx    Specifies which extension OID to send. Use (0) to get the first one.

       void * oid  a pointer to a structure to hold the OID (may be null)

       size_t * oid_size
		   initially holds the size of	oid

DESCRIPTION
       This  function  will  return  the requested extension OID in the certificate.  The extension OID will be stored as a string in the provided
       buffer.

       The  oid returned will be null terminated, although  oid_size will not account for the trailing null.

       able GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
