# CL_Display::flip

Flip back buffer to front, making changes visible on screen.

    	void flip(
    		int interval = -1);

Parameters:

interval
  Specifies the minimum number of video frames that are displayed before a buffer swap will occur.

Detailed description:

The parameter interval specifies the minimum number of video frames that are displayed before a buffer swap will occur.

A video frame period is the time required by the monitor to display a full frame of video data. In the case of an interlaced monitor, this is typically the time required to display both the even and odd fields of a frame of video data. An interval set to a value of 2 means that the color buffers will be swapped at most every other video frame.

If interval is set to a value of 0, buffer swaps are not synchronized to a video frame. The interval value is silently clamped to the maximum implementation-dependent value supported before being stored.

If interval is set to a value of -1 (the default), then it will use the buffer swap used for previous flip. If its the first flip, it will use the system default, which per default is 1.
