extern

[BaharPamuk]

Hi all,

I want to reach a variable in another file without including the file. Does "extern" do this? Or are there any way of doing this?

I understand as "extern" does this in the tutorials, but when i try some basic examples, it didn't work.

Thanks.

If you have
int foo;
in one C file, then

extern int foo;
in another C file will allow you to access that variable.

Post what you tried, rather than just saying "it didn't work".

Have you by any chance defined it as extern in all the files?

Yes that was the cause of the mistake.
