From: =?UTF-8?B?UmFmYcWCIE1pxYJlY2tp?= To: linux-wireless@vger.kernel.org Content-Type: text/plain; charset=UTF-8 Sender: linux-wireless-owner@vger.kernel.org List-ID: I want to create module library, which will handle PHY operations on Broadcom card. For most of the time, I'm going to call library functions from b43. However, there are places where I need to call some (b43) driver function from library module. How can I handle that? Should I pass some functions pointers to the library? Is that going to work? Or is there a better approach? P.S. I'm asking at linux-wireless, it's not wireless related however. I think question is quite simple for C hackers and there is no need to hit LKML. -- Rafał
