Reflex Member Invoke Parameter ret

ROOT
1

I’m a bit confused. I noticed the first parameter of Member::Invoke is T& ret. But the documentation doesn’t say what that parameter is used for. This is my code:

void call(std::string fname)
{
	Reflex::Type T = Reflex::Type::ByName(fname);
	Reflex::Member M = T.MemberAt(1);
	int tst = 0;
	M.Invoke<int>(tst);
}

Using that empty int, I’m getting:

Unhandled exception at 0x52167D3A (libReflex.dll) in application.exe: 0xC0000005: Access violation reading location 0x0000006F.

I’m on Windows and using the prebuilt debug version of ROOT. I have Visual Studio Express 2012 for Windows Desktop.

Hi,

[quote=“kirbyfan64sos”]I’m on Windows and using the prebuilt debug version of ROOT.

You should use Visual Studio 2010 to compile your code (assuming you downloaded the VC10 version of ROOT)

Cheers, Bertrand.

Ok. I tried VS 2010 and it works.
