  12. Or just use my favourite all purpose converter, sscanf().  Something
  13. like this works:
  14.  
  15. char *hex = "0x11";
  16. int  num;
  17.  
  18. sscanf(hex,"0x%x",&num);
  19.  
  20. --> num contains 17 as expected.
  21.  
  22. And of course you can go the other way too, using it's counterpart
  23. sprintf().
  24.  
  25. Good luck
