It's a forward declaration.
Consider two structures that have pointers to each other:
struct a {
int b, c, d;
struct *b b_ptr;
}
struct b {
int foo, bar, baz;
struct *a a_ptr;
}
Now, the struct *b in the first structure won't compile because it hasn't
seen b yet. So we stick a 'struct b;' in front both of them so struct a can
compile successfully.
