Since my data was 12 bytes long I was lucky there happened to be a data type 16 bytes long a "long double" I just filled the first 4 bytes with zeros and

C++
;
struct usingrange
{
	ESDID esdid;
	int start;
	int end;
	
	usingrange() { start = 0; end = 0; return; }
  bool operator<(const usingrange& x) const {
	  union
	  {
		  long double a;
		  char str1[16];
	  }c;
	  union
	  {
		  long double b;
		  char str2[16];
	  }d;
	
	  ::memset(&c.str1, 0x00, 16);
	  ::memset(&d.str2, 0x00, 16);
	  ::memcpy(&c.str1[4], &esdid, 4);
	  ::memcpy(&c.str1[8],&start,4);
	  ::memcpy(&c.str1[12], &end, 4);
	  ::memcpy(&d.str2[4], &x.esdid, 4);
	  ::memcpy(&d.str2[8], &x.start, 4);
	  ::memcpy(&d.str2[12], &x.end, 4);

	  return c.a < d.b;

	//	  return usingrange  < x;
	//	  if (start < x.start) 
     //   return start < x.start;
//		  return x.end < end;

 }
 
};
