    Returns a new mouse event.
    The event source may be taken from another event, or may be NULL. mouseType should be one of the mouse event types. mouseCursorPosition should be the position of the mouse cursor in global coordinates. mouseButton should be the button that's changing state; mouseButton is ignored unless mouseType is one of EventOtherMouseDown, EventOtherMouseDragged, or EventOtherMouseUp.
    
    The current implemementation of the event system supports a maximum of thirty-two buttons. Mouse button 0 is the primary button on the mouse. Mouse button 1 is the secondary mouse button (right). Mouse button 2 is the center button, and the remaining buttons are in USB device order.

```
    Returns a new keyboard event.
    The event source may be taken from another event, or may be NULL. Based on the virtual key code values entered, the appropriate key down, key up, or flags changed events are generated.
    
    All keystrokes needed to generate a character must be entered, including SHIFT, CONTROL, OPTION, and COMMAND keys. For example, to produce a 'Z', the SHIFT key must be down, the 'z' key must go down, and then the SHIFT and 'z' key must be released:
```
 CGEventCreateKeyboardEvent(source, (CGKeyCode)56, true);  // shift down
 CGEventCreateKeyboardEvent(source, (CGKeyCode) 6, true);  // 'z' down
 CGEventCreateKeyboardEvent(source, (CGKeyCode) 6, false); // 'z' up
 CGEventCreateKeyboardEvent(source, (CGKeyCode)56, false); // 'shift up

```
    Returns a new scrollwheel event.
    The event source may be taken from another event, or may be NULL. The scrolling units may be specified in lines using ScrollEventUnitLine or in pixels using ScrollEventUnitPixel. ScrollEventUnitPixel will produce an event that most applications interpret as a smooth scrolling event.
    
    One or more wheels must be specified. The current implementation supports up to three wheels.
    
    Every scrollwheel event can be interpreted to be scrolling by pixel or by line. The scale between the two is about 10 pixels per line by default. The scale can be altered by setting a custom value for the event source, using CGEventSourceSetPixelsPerLine.

```
    Creates an event tap.
    Taps may be placed at the point where HIDSystem events enter the server, at the point where HIDSystem and remote control events enter a session, at the point where events have been annotated to flow to a specific application, or at the point where events are delivered to the application. Taps may be inserted at a specified point at the head of pre-existing filters, or appended after any pre-existing filters.
    
    Taps may be passive event listeners, or active filters. An active filter may pass an event through unmodified, modify an event, or discard an event. When a tap is registered, it identifies the set of events to be observed with a mask, and indicates if it is a passive or active event filter. Multiple event type bitmasks may be ORed together.
    
    Taps may only be placed at HIDEventTap by a process running as the root user. NULL is returned for other users.
    
    Taps placed at HIDEventTap, SessionEventTap, AnnotatedSessionEventTap, or on a specific process may only receive key up and down events if access for assistive devices is enabled (Preferences Accessibility panel, Keyboard view) or the caller is enabled for assistive device access, as by AXMakeProcessTrusted. If the tap is not permitted to monitor these events when the tap is created, then the appropriate bits in the mask are cleared. If that results in an empty mask, then NULL is returned.
    
    An event tap is represented as a CFMachPortRef. The event tap may be added to an appropriate run loop by calling CFRunLoopAddSource.
    
    Releasing the CFMachPortRef will release the tap.
    
    A CGEventTapProxy is an opaque reference to state within the client application associated with the tap. The tap function may pass this reference to other functions, such as the event-posting routines.
    
    The event tap callback runs from the CFRunLoop to which the tap CFMachPort is added as a source. Thread safety is defined by the CFRunLoop and its environment.

    You can use this function to post a new event at the same point to which an event returned from an event tap callback function would be posted.

```
    Gets a list of currently installed event taps.
    tapList is an array of event tap information structures of length maxNumberOfTaps. You are responsible for allocating storage for this array. On return, your array contains a list of currently installed event taps. On return, the number of event taps that are currently installed is stored in eventTapCount. If you pass NULL in this parameter, the maxNumberOfTaps parameter is ignored, and the number of event taps that are currently installed is stored in eventTapCount.
    
    Each call to this function has the side effect of resetting the minimum and maximum latencies in the tapList parameter to the corresponding average values. Values reported in these fields reflect the minimum and maximum values seen since the preceding call, or the instantiation of the tap. This allows a monitoring tool to evaluate the best and worst case latency over time and under various operating conditions.
