0x0 = start address, 0x17fff = end address. The address 0x17fff was not found in the current device’s address space.
This can happen because 0x0 can be stored in a variable and 0x17fff can be stored as an array index. This is bad. What we do instead is store the start address of the device in a variable and the end address in an array index. Then, we check what the offset is and if 0x0 is in another variable, we look for 0x17fff.
It’s not great but it works. The problem is that it requires a bit of thinking. You can’t just copy and paste the two variables and have them both work. The best way to fix this is to use the array index as a pointer.
I think it’s a good idea to create a variable to hold the start address and end address. It would be great if it was just 10 bytes, but that’s not the case in real life. The best way to fix this is to use the array index as a pointer.
To access the start address, you would use the.c address of the variable. To access the end address, you would use 0x17fff. Now to make both work, we have to be aware of address alignment. The start address is the first byte of the variable. If the variable is on a 32/64-bit system, then it is 32 bits. If the variable is on a 64-bit system, then it is 64 bits.
The start address is the first byte of the start address, and the end address is the first byte of the end address. In the example above, the start address is 32 bits, and the end address is 33 bits. We can’t just add a 0x17fff to the start address, because that would result in a 16-bit address in the end address. Instead, we have to subtract 0x017fff from the start address.
Because the variable is on a 3264-bit system, the start address is 0x0, and the end address is 0x17fff. The start address is all that there is to the address range.
Now, 0x17fff has a value of 53480, which is the hexadecimal value of 0xFFFFF7F. However, we want to find a way to set the start address to 0x0 as well, so that the address range is from 0x0 to 0x17fff. This is accomplished by subtracting 0x017fff from the start address.
We can then subtract 0x017fff from the start address, using the value of 0x017fff, and you’re done. You can then subtract 0x017fff from 0x017fff from the start address, and you’re out of luck. What you need to do is replace 0x017fff with 0x016fff, and you’re out of luck.
There’s a reason that you can’t use addresses greater than 0xFFFFFFFF, and that you cannot subtract 0xFFFFFFFF from an address. You might be thinking that this is what we mean when we say “subtracting from 0xFFFFFFFF”. So let’s do that. We can do that by subtracting 0xFFFFFFFF from 0xFFFFFFFF, and youre out of luck.
