You'd define the type of the struct in the header file, and declare (but not define) MEM_IO_PTRS in the header using extern:

Code:
/* in header file */

struct mem_ptrs
{
    ... /* members */
};

extern struct mem_ptrs MEM_IO_PTRS[10];

And then in one of your C files you'd define MEM_IO_PTRS:

Code:
/* in source file */

struct mem_ptrs MEM_IO_PTRS[10];
