glXWaitGL(3)

NAME

       glXWaitGL - complete GL execution prior to subsequent X calls

C SPECIFICATION

       void glXWaitGL( void )

       delim $$

DESCRIPTION

       GL  rendering  calls  made prior to glXWaitGL are guaranteed to be exe-
       cuted 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       no longer valid.
