Hi,
I haven't seen the source in question, but if you declared a
pointer to a structure, you would have to malloc and free it since it
would appear on the heap. If you declare it as normal and pass a
reference to it (&), then the space is created in the stack, when the
variable is declared and freed when the function exits.
Of course, I could be wrong as I frequently get "heap" and "stack"
mixed up (and am always too lazy to look it up myself :-) ).
