Pointer:constructor()

Pointer:constructor([cobj])constructor

The Pointer constructor creates a new Pointer instance, that points to the memory address of the C value represented by the provided C object instance.

Parameters

[cobj]

A C object instance to point to, which can be any of the following :

Value
Struct
Union
[] Array

Notes

Calling the constructor without any arguments will return a NULL C pointer.
Only Cvalues can be pointed to (C definition objects can't be used).

Return value

The constructor returns a new Pointer instance.

Example


--! luart-extensions
import c

-- Creates a C int Value
local int = c.int(1250)

-- Creates a Pointer to this int Value
local c_ptr = c.Pointer(int)

-- Prints the pointer
print(c_ptr)

-- Prints the pointer content
print(c_ptr.content)
