As someone mentioned before, the initialization to 0 or NULL
is pointless here, as the variables are always assigned before
they are used. There are a number of other places in your
code that do similar things, you should probably go through
these and remove the initializers.
If you indeed need something to be initialized, it is good practice
to do the initialization as late as possible, e.g.
int foo;
...
foo = 0;
do_foo(foo);
to make it clear that you have a reason to initialize it.
