Question about function pointers

[MrDoomMaster]

I'm trying to create a typedef which can create a function pointer to a function which returns void and has no parameters, such as the example delcaration you see below:

void TestFunc(void);

I've tried the following:

typedef void (*_FuncPtr)(void);

So, if I do this:

_FuncPtr FunctionPtr = TestFunc;

FunctionPtr();

The compiler returns an error saying that FunctionPtr does not evaluate to a function taking 0 arguments.

How would I appropriately create a function pointer such as this?

Thanks!
