NAME

       glutSwapBuffers - swaps the buffers of the current window if double buffered.

SYNTAX

       #include <GLUT/glut.h>

       void glutSwapBuffers(void);

DESCRIPTION

       Performs  a buffer swap on the layer in use for the current window.  Specifically, glutSwapBuffers promotes the contents of the back buffer
       of the layer in use of the current window to become the contents of the front buffer. The contents of the back  buffer  then  become  unde-
       fined.  The  update  typically  takes  place  during  the vertical retrace of the monitor, rather than immediately after glutSwapBuffers is
       called.

       An implicit glFlush is done by glutSwapBuffers before it returns.  Subsequent OpenGL commands  can  be  issued  immediately  after  calling
       glutSwapBuffers, but are not executed until the buffer exchange is completed.

       If the layer in use is not double buffered, glutSwapBuffers has no effect.

NAME

     glutSwapBuffers -- Swaps the buffers for the current window.

LIBRARY

     OpenGLUT - window

SYNOPSIS

     #include <openglut.h>

     void
     glutSwapBuffers(void);

DESCRIPTION

     This function signals to OpenGLUT that you are done drawing to the  current window   for now.  If your window is double-buffered (  GLUT_DOU-
     BLE  param to glutInitDisplayMode()), then OpenGLUT will swap the front buffer with the back buffer.

     This also computes your current frame-rate and prints the result on  stderr  if indicated by the  GLUT_FPS  environment variable.	The com-
     puted value is not necessarily the total frame rate, if you have multiple windows, as the statistic is the total number of buffer-swaps for
     the entire program.

CAVEATS

     This function has no effect if your window is  GLUT_SINGLE  .

     Frame rate is only calculated for double-buffered windows.

TODO

     How does this interact with overlays?

     Consider making  GLUT_FPS	keep per-window stats in a multi-window program.
