int a[Array_size][Array_size] = { { 0 } }; To avoid leaving variables uninitialized, you can initialize their values after declaring them. For instance, if you wish to set all values to 0, you may use the following approach:
To define a MiniportInitializeEx function, you must first provide a function declaration that identifies the type of function you're defining. Windows provides a set of function types for drivers.
