Subject: exporting variables across modules
Date: Fri, 11 May 2007 09:02:01 +0530 [thread overview]
Message-ID: <005601c7937c$f5416580$142ec70a@dlh.st.com> (raw)
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.
Regards,
Bhuvan
