Whilst porting some C code I keep encountering pointers being passed to functions as arguments. For example:



I have decided to have a stab at replicating this code in DBP as follows:



I'm not sure I can use the * in quite this way in DBP but we shall see if it works or not! LOL.

Cheers

That wont work - what you need to do is pass the memory address, and the use either mine or IanM's peek/poke routines to get the data out of the memory address. If you dont want to do that, you can do something like :

value=*addr

and then increase addr by 1,2/4 bytes etc

Good news everyone! I really am THAT good...

Ok! Thanks. I'm going to try the variable = pointer method first and then if that fails, I'll try and use your peek/poke routines.
