Same code in more than one cogs

EMHmark7

Hi,

In SPIN on Propeller.

If I use a function in several cogs and I declare variables in it of same name in all instances (because same source code),
will it create separate instances of those variables?

I suppose yes, but wanted to make sure.

In fact, I want to copy paste codes that looks alike in 2 different functions but with same local variable names.

Thanks,
Marc

If you're referring to local variables (the ones after |) then yes, you get separate ones for each call/instance. Remember that they remain uninitialised (not zero'd, except result).

You don't get separate global variables for each instance, but you do get separate locals, as Heater said. So you can cognew the same function twice. Make sure each cog gets its own stack space, though.

As Marko pointed out, when you launch a Spin method into its own cog, you do in fact get separate copies of the local variables for that method -- these will live in the stack space that you declare for the cog. Also, as pointed out, these variables are not initialized and you don't have access to them outside the method.
