javascript - Unwrap a UInt64 that is wrapped in a voidptr_t -

in js-ctypes have received windows handle (voidptr_t). in cases handle null, returned me as

var ret = ctypes.voidptr_t(ctypes.uint64('0x0'))

i want disclose voidptr_t , ctypes.uint64.compare(ret, ctypes.uint64('0x0')).

right i'm doing funky thing:

if (local_hwnd.tostring().indexof('uint64("0x0")') > -1) { console.log('has no handle 0 local_hwnd.tostring() = ', local_hwnd.tostring()); }

for simple null comparisons:

ptr.isnull()

for unwrapping stuff (to uint64):

ctypes.cast(ptr, ctypes.uintptr_t).value
