exporting variables across modules

From: Bhuvan Kumar MITTAL

I have 2 kernel modules. In one module I have 2 global pointers(of type unsigned char and int respectively). I'd like to use these 2 pointers in the other module. I am adopting the following approach but not really sure whether its right or not:

1. I have exported both the pointers using EXPORT_SYMBOL(sym1) and EXPORT_SYMBOL(sym2)

2. Then in the module in which I want to use these pointers I have declared these 2 pointers as global extern variables as:
extern unsigned char * sym1;
extern unsigned int * sym2;

Is this the right way to use these pointers? Kindly guide me.
