Includes

[Gav]

I am trying to make a Code Library with all my most used functions in so I
can just include them and use them. The problem is when a program includes
an include that also includes something that has already been included (tongue
twister).

ie.
Program A - Includes B and C.

But include B also includes C. So when the program tries to include C it
has already been included. Is there any way of detecting what has already
been included?

Cheers Gav

The same way we do it with C programming. At the top of each file, define a
variable or constant. Before including that file, check for the existence of
that variable - if it exists don't include that file.
