I have need to access the type of the parameter used to construct a
parameterized structure:
local Vector = ffi.typeof("struct { int n; int Capacity; $ *Data; }",
ct);
Is there any way to get at what 'ct' was from within a metamethod?
I can find out how large it is by doing ffi.sizeof(instance.Data[0])
but, all I get out of ffi.typeof(instance.Data) is "struct 102".
Alternative, could I use "struct 102" in any meaningful way, like
ffi.new("struct 102", 100);
