Native Function Calls

1. Creating a Native Function Object

Use native.new_function to create a wrapper for a native function address.

local func = native.new_function(address, returnType, paramTypes)

• address: The memory address of the native function (Long).
• returnType: The return type string. Supported: "void", "int", "float", "double", "pointer".
• paramTypes: A table containing parameter type strings. Supported: "int", "float", "double", "pointer".

Example:

local base = native.resolve_symbol("libexample.so", "some_exported_func")
local func = native.new_function(base, "void", {"int", "int"})

2. Invoking the Function

Once the function object is created, you can call it directly.

func(arg1, arg2...)

• Pass arguments directly.
• The return value matches the specified returnType.

Example:

func(10, 20)
