This snippet of code, help me to finish it well.

This code is taken completely from the site. I do not understand him at all. Functions are declared, but not registered. What is this? Are these functions not system, not library? Why are they not described?
It looks like a pathetic snippet of code.

If possible, can you finish it?

Code:

#include <windows.h>

VOID MouseEventProc(MOUSE_EVENT_RECORD);
VOID ResizeEventProc(WINDOW_BUFFER_SIZE_RECORD);
VOID KeyEventProc(KEY_EVENT_RECORD);
VOID GetInputEvents(VOID);

int main()
{
    HANDLE hStdin;
    DWORD cNumRead, fdwMode, fdwSaveOldMode, i;
    INPUT_RECORD irInBuf[128];

    // Получим стандартный дескриптор ввода.

    hStdin = GetStdHandle(STD_INPUT_HANDLE);
    if (hStdin == INVALID_HANDLE_VALUE)
        MyErrorExit("GetStdHandle");

    // Сохраним текущий режим ввода для будущего восстановления при
    // выходе из программы.

    if (! GetConsoleMode(hStdin, &fdwSaveOldMode) )
        MyErrorExit("GetConsoleMode");

    // Включим события ввода от мыши и окна.

    fdwMode = ENABLE_WINDOW_INPUT | ENABLE_MOUSE_INPUT;
    if (! SetConsoleMode(hStdin, fdwMode) )
        MyErrorExit("SetConsoleMode");

    // Цикл чтения и обработки событий ввода.

    while (1)
    {

    // Ожидание событий.

        if (! ReadConsoleInput(
                hStdin,      // дескриптор буфера ввода
                irInBuf,     // буфер, в котором читаем
                128,         // размер буфера чтения
                &cNumRead) ) // число прочитанных записей
            MyErrorExit("ReadConsoleInput");

   // Направляем события соответствующим обработчикам.

        for (i = 0; i < cNumRead; i++)
        {
            switch(irInBuf[i].EventType)
            {
                case KEY_EVENT: // ввод с клавиатуры
                    KeyEventProc(irInBuf[i].Event.KeyEvent);
                    break;

                case MOUSE_EVENT: // ввод от мыши
                    MouseEventProc(irInBuf[i].Event.MouseEvent);
                    break;

                case WINDOW_BUFFER_SIZE_EVENT: // изменение размера
                                               // экранного буфера
                    ResizeEventProc(
                        irInBuf[i].Event.WindowBufferSizeEvent);
                    break;

                case FOCUS_EVENT:  // игнорирование событий фокуса

                case MENU_EVENT:   // игнорирование событий меню
                    break;

                default:
                    MyErrorExit("unknown event type");
                    break;
            }
        }
    }

    return 0;
}

Yes, those function definitions are missing and need to be provided. It's not really possible for someone to complete them for you since it's up to you (or the original author) to decide what you want them to do.

However, the code seems to have been (badly) copied from here, so perhaps those definitions will do. In fact, you're probably best to toss out the code you have and just use the code from the MS site.
