If you initialise your ints to a full 4 byte value, such as 0x11223344 you will get a clearer picture of what is happening. Most C compilers align N word values to an N word boundary. Hence you probably have 3 bytes of padding between the char and the first int. These pad values are picking up whatever is in memory at that point. They seem to have their top bits set, so C is treating them as negative numbers and printf is sign extending the value to a full 32 bits, because you are using %x which expects an integer argument. If you use %c, or %2.2x the bytes will look more as you expect. -- Matthew JONES http://www.tandbergtv.com/
