Compiler won't accept valid code? error C2447: '{': missing function header (old-style formal list?)

Question

Just want to start by saying thank you for taking the time to look at my problem.

Below is the code that is giving me the error:

// INFO(Tanner): XInputGetState Support
#define X_INPUT_GET_STATE(name) DWORD WINAPI name(DWORD dwUserIndex, XINPUT_STATE* pState);
typedef X_INPUT_GET_STATE(x_input_get_state);

X_INPUT_GET_STATE(XInputGetStateStub)
{
    return(ERROR_DEVICE_NOT_CONNECTED);
}
global_variable x_input_get_state* XInputGetState_ = XInputGetStateStub;
#define XInputGetState XInputGetState_


// INFO(Tanner): XInputSetState Support
#define X_INPUT_SET_STATE(name) DWORD WINAPI name(DWORD dwUserIndex, XINPUT_VIBRATION* pVibration);
typedef X_INPUT_SET_STATE(x_input_set_state);

X_INPUT_SET_STATE(XInputSetStateStub)
{
    return(0);
}
global_variable x_input_set_state* XInputSetState_ = XInputSetStateStub;
#define XInputSetState XInputSetState_

The problem accoring to the compiler is that I don't have the open currly brace "{" for my XInputGetStateStub and XInputSetStateStub.

Any help is appriciated!

Your code will preprocess to the following:

typedef DWORD WINAPI x_input_get_state(DWORD dwUserIndex, XINPUT_STATE* pState);;

DWORD WINAPI XInputGetStateStub(DWORD dwUserIndex, XINPUT_STATE* pState);
{
    return(ERROR_DEVICE_NOT_CONNECTED);
}
global_variable x_input_get_state* XInputGetState_ = XInputGetStateStub;

typedef DWORD WINAPI x_input_set_state(DWORD dwUserIndex, XINPUT_VIBRATION* pVibration);;

DWORD WINAPI XInputSetStateStub(DWORD dwUserIndex, XINPUT_VIBRATION* pVibration);
{
    return(0);
}
global_variable x_input_set_state* XInputSetState_ = XInputSetStateStub;

As you can see there is an extra ; after the DWORD WINAPI XInputSetStateStub(DWORD dwUserIndex, XINPUT_VIBRATION* pVibration) due to #define ending with a ;. Remove that, and see if it works or not.
