Initialize artDmxCallback as NULL #50

Closed niliha closed 1 year ago

niliha commented 1 year ago

When not explicitly setting artDmxCallback via setArtDmxCallback(), it may point to an invalid address other than NULL, since primitive pointers are not initialized by the compiler in c++.

Since read() tries to dereference artDmxCallback if it's not NULL, the program may crash.

As an easy fix, I suggest to initialize artDmxCallback as NULL in the initializer list.

That is a very good idea! Thanks.
