Pointer length operator | LuaRT free and open source Windows programming framework for Lua

# Pointer length operator

The length operator # applied on a Pointer object returns the size in bytes of the pointer on the current execution context, depending on the LuaRT interpreter used (x86 or x64).

Notes

The length operator returns the same result as the Pointer.size property.

Example


local c = require "c"

-- function to get current interpreter architecture (same as _ARCH global variable)
local function get_arch()
    return #c.NULL == 8 and "x64" or x86
end

print("You are using the "..get_arch().." LuaRT interpreter")
