SetVariableValuePtr

SetVariableValuePtrMethod

Sets the value of a Pointer variable

Syntax

SetVariableValuePtr(Value)

Parameters

Value

Pointer

Pointer that the variable will be set to

Returns

Nothing

Remarks

This lets you set the value of a Pointer variable defined with DefineVariable (or Define) . Note: This does not change the Pointer of the variable. It simply stores a Pointer value in the variable.

Dim x = uc.DefineVariable("x As Int16 = -1")
Dim MyPointer = uc.DefineVariable("xPtr As Pointer")

MyPointer.SetVariableValuePtr(x.ValueAddr())
Console.WriteLine(uc.EvalStr("ValueAt(Int16u, xPtr)")) ' Returns 65535


          
var x = uc.DefineVariable("x As Int16 = -1");
var MyPointer = uc.DefineVariable("xPtr As Pointer");

MyPointer.SetVariableValuePtr(x.ValueAddr());
Console.WriteLine(uc.EvalStr("ValueAt(Int16u, xPtr)")); // Returns 65535;


          
//var x = uc.DefineVariable('x As Int16 = -1');
//var MyPointer = uc.DefineVariable('xPtr As Pointer');

      MyPointer.SetVariableValuePtr(x.ValueAddr());
      WriteLn(uc.EvalStr('ValueAt(Int16u, xPtr)')); // Returns 65535;


          
auto x = uc.DefineVariable("x As Int16 = -1");
auto MyPointer = uc.DefineVariable("xPtr As Pointer");

MyPointer.SetVariableValuePtr(x.ValueAddr());
cout << uc.EvalStr("ValueAt(Int16u, xPtr)") << endl; // Returns 65535;


          
auto x = uc.DefineVariable("x As Int16 = -1");
auto MyPointer = uc.DefineVariable("xPtr As Pointer");

MyPointer.SetVariableValuePtr(x.ValueAddr());
Console::WriteLine(uc.EvalStr("ValueAt(Int16u, xPtr)")); // Returns 65535;
