glXWaitGL.3gl

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.
