Title: Why int 3(0xCC) was used for padding?
Post by: nobody on November 01, 2005, 09:53:26 AM

Could we use other instruction for padding?
Thanks!

Sure you can use another instruction for padding, but it won't do the same thing. For 0xCC, you want "int3" (no space) not "int 3" (with a space... this forum software is apt to butcher spaces) - not quite the same thing. What is it you want to do?

Best,
Frank

A common thing to use for padding is NOP, or 0x90.
