getenv in Visual C++ 2012

I want to use a getenv function from C in my C++ project in Visual Studio 2012.

The code:

extern "C" System::SByte^ getenv(const System::SByte^ name);

and then in some function:

String^ h1 = "HOMEDRIVE";
const System::SByte^ c1 = dynamic_cast<const System::SByte^>(h1);
getenv(c1);

The error I get:

Error   11  error LNK2019: unresolved external symbol "extern "C" class System::SByte ^ __clrcall getenv(class System::SByte const ^)" (?getenv@@$$J0YMP$AAVSByte@System@@P$ABV12@@Z) referenced in function "public: void __clrcall Kameleon::Form1::createConfig(void)" (?createConfig@Form1@Kameleon@@$$FQ$AAMXXZ)   C:\Users\Michal\Desktop\Kameleon\Kameleon\Kameleon\Kameleon.obj Kameleon

I think for C++ project you can use getenv from <cstdlib>, not C++/CLI one.
