Hello,
I was playing around with LuaJIT's FFI today and noticed a peculiarity
and was curious...
Is there a reason why the following snippet of code prints:
true true nil
When I would expect it to be:
true true true
----------------------
ffi = require('ffi')
ffi.cdef[[
typedef struct foo { int a, b; } foo_t;
]]
typeFoo = ffi.typeof('foo_t')
foo = typeFoo()
typeList = {}
typeList[typeFoo] = true
print( typeFoo==ffi.typeof(foo), typeList[typeFoo],
typeList[ffi.typeof(foo)] )
----------------------
Thanks,
Jeff
