I have 2 files: `Sod/iload/iload.c` and
`Item/itemrule/itemrule.c`, and I want to access a variable defined in iload.c which is defined in itemrule.c.

To do this, I made and defined a global variable in iload.c, and I tried to access this variable in itemrule .c with the extern keyword, but it is always 0.

I'm worried that it might be because the files have different paths, does anyone know how I can access this variable?
