   In a multi-source project I have a global array, declared as:

     char my_global_array[256];

   in one of the modules.

   Which is the best way of declaring it on the other modules?

     extern char my_global_array[256];
     extern char *my_global_array;
     extern char my_global_array[];


extern char my_global_array[256];

Extern declarations MUST exactly match the corresponding global definition,
with the exception of any initializer clause.

The variable my_global_array is NOT a pointer it is an array and you cannot
declare an undimensioned array except as an automatic argument, so....
