glFlush(3G)		       OpenGL Reference			   glFlush(3G)

NAME    [Toc]    [Back]

     glFlush - force execution of GL commands in finite	time

C SPECIFICATION    [Toc]    [Back]

     void glFlush( void	)

DESCRIPTION    [Toc]    [Back]

     Different GL implementations buffer commands in several different
     locations,	including network buffers and the graphics accelerator itself.
     glFlush empties all of these buffers, causing all issued commands to be
     executed as quickly as they are accepted by the actual rendering engine.
     Though this execution may not be completed	in any particular time period,
     it	does complete in finite	time.

     Because any GL program might be executed over a network, or on an
     accelerator that buffers commands,	all programs should call glFlush
     whenever they count on having all of their	previously issued commands
     completed.	 For example, call glFlush before waiting for user input that
     depends on	the generated image.

NOTES    [Toc]    [Back]

     glFlush can return	at any time.  It does not wait until the execution of
     all previously issued GL commands is complete.

ERRORS    [Toc]    [Back]

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