Complement to GetCommandLine for getting the argument count?

Working in Windows C++ and using GetCommandLine to get the arguments in a function. Is there a similar function which would return the number of arguments in the command line?

I am unable to get it from main because I am using the 

int WINAPI _tWinMain(HINSTANCE /*hInstance*/, 
    HINSTANCE /*hPrevInstance*/, 
    LPTSTR /*lpCmdLine*/, 
    int /*nShowCmd*/)

main function.

The way is to use another API with GetCommandLine

int numArgs = 0;
LPCWSTR *argv[] = CommandLineToArgvW(GetCommandLineW(), &numArgs);

Now in numArgs a count of arguments, in argv a pointer to an array of arguments. CRT startup code uses this function to build argv

argv[0] is a name of module, argv[n], with n > 0 is a arguments of line, stripped by space
