C SPECIFICATION    [Toc]    [Back]

     void glFinish( void )

DESCRIPTION    [Toc]    [Back]

     glFinish does not return until the	effects	of all previously called GL
     commands are complete.  Such effects include all changes to GL state, all
     changes to	connection state, and all changes to the frame buffer
     contents.

     Such effects also include asynchronous GL commands, if the	SGIX_async
     extension is implemented.

NOTES    [Toc]    [Back]

     glFinish requires a round trip to the server.

ERRORS    [Toc]    [Back]

     GL_INVALID_OPERATION is generated if glFinish is executed between the
     execution of glBegin and the corresponding	execution of glEnd.


MACHINE	DEPENDENCIES
     The SGIX_async and	SGIX_async_pixel extensions are	implemented only on
     Octane2 VPro systems.
