a special type of function

[Sheldon]

Hi,

I want to write function that is of type: void Funt(long az, double
bt, long *ar1, double *ar2)
I got the function to work for the arrays: ar1 and ar2 but I don't
know how to get it to work for variables: az and bt.

Can anyone show me if and how this is possible.

Thanks,
/Sheldon

If you want to modify the contents of the variables az and bt, you
have to pass their addresses.
In C, all objects passed into functions are copies of the original.
So if you want to change the original object, just pass in the address
of the object and manipulate it that way.

This is just my guess, and my Karnak hat has gone missing so if you
really want to know about something else, you might spell out exactly
what you have tried and exactly what is going wrong, along with a copy/
paste of the actual code you are using.

Absolutely the simplest way to do this is to write:

void Funt(long az, double bt, long *ar1, double *ar2) {}

If that doesn't meet your needs (I certainly don't expect it to), then
you're going to have to tell us what you're actually having problems
with. What have you tried to do, and how has it failed?

I can tell you this - there's nothing about your function type that is a
problem. It might not be appropriate for the purpose for which you
intend to use that function, but in order to address that issue we have
to know what the intended use is.

Thanks! It works!
