+# *ctypes* Library

+A library for safe work with C types.

+Usage examples:
+
+```lua
+local x = ctypes.uint64(1234)
+print(x) --> 1234ULL (cdata)
+local y = ctypes.uint64("18446744073709551615")
+print(y) --> 18446744073709551615ULL (cdata)
+print(x + y) --> 1233ULL
+
+local z = tonumber(x)
+print(z) --> 1234 (number)
