Quiz for next Friday. What are these and what's the difference between
them:
int (*(**p)[])(int)
declare p as pointer to pointer to array of pointer to function (int)
returning int
and
int *(*(**p)[])(int)
declare p as pointer to pointer to array of pointer to function (int)
returning pointer to int
I would really want to see both a justification of method and
certificate of sanity to someone who actually used either. I can just
barely justify pointer to array of function returning int (state
machines), these look like something a compiler compiler would do.
I sort of recall using a pointer to an array of structs as the basic
data type for anything significant in C but I've mostly forgotten why.
I think sometimes it had to do with getting usable semantics to access
things in shared memory segments.
