Getting keyboard input

[finaiized]

I'm using SFML's C Binding, and I'm trying to get input from the keyboard.

Code: [Select]

while (sfRenderWindow_IsOpened(App))
    {
        while (sfRenderWindow_GetEvent(App, &Event))
        {
            Input = sfRenderWindow_GetInput(App);
            if (Event.Type == sfEvtClosed)
                sfRenderWindow_Close(App);
            if (Event.Type == sfEvtKeyPressed) {
            if (sfInput_IsKeyDown(Input, sfKeyCode.sfKeyA)) {
            sfRenderWindow_Close(App);
           
            }
        }

I have the above code right now, but looking at the C++ tutorials, and the API, I have a feeling that I should either use Event.Type == sfEvtKeyPressed OR sfInput_IsKeyDown. This leads me to two questions:

1) Which way should I use in a game loop?
2) If it is using Event.Type == sfEvtKeyPressed, what code do I use to check the contents of Event for a key?

Thanks for your time!    I've been trying everything and I'm guessing it isn't too hard but it isn't hitting me.

Looks like I overlooked something, the answer is quite simple! In the while loop for GetEvent(),

Code: [Select]

        if (Event.Type == sfEvtKeyPressed) {
        if (Event.Key.Code == sfKeyA) {
        sfRenderWindow_Close(App);
        }
will hook on to the Key A.
