Gets a pointer to the Data. Can be used with libraries such as LuaJIT's FFI.

O.png Use at your own risk. Directly reading from and writing to the raw memory owned by the Data will bypass any safety checks and thread-safety the Data might normally have.  


O.png Since LÖVE 11.3, Data:getFFIPointer is a preferred alternative because it can work with new 64-bit architectures.  


Function

Synopsis
