glXWaitGL(3G)		    OpenGL Reference - GLX		 glXWaitGL(3G)



NAME
     glXWaitGL - complete GL execution prior to	subsequent X calls


C SPECIFICATION
     void glXWaitGL( void )



DESCRIPTION
     OpenGL rendering calls made prior to glXWaitGL are	guaranteed to be
     executed before X rendering calls made after glXWaitGL.  Although this
     same result can be	achieved using glFinish, glXWaitGL does	not require a
     round trip	to the server, and it is therefore more	efficient in cases
     where client and server are on separate machines.

     glXWaitGL is ignored if there is no current GLX context.


NOTES
     glXWaitGL may or may not flush the	X stream.


ERRORS
     GLXBadCurrentWindow is generated if the drawable associated with the
     current context of	the calling thread is a	window,	and that window	is no
     longer valid.
