fglFinish(3G) OpenGL Reference fglFinish(3G)NAME
fglFinish - block until all GL execution is complete
FORTRAN SPECIFICATION
SUBROUTINE fglFinish( )
DESCRIPTION
fglFinish 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
fglFinish requires a round trip to the server.
ERRORS
GL_INVALID_OPERATION is generated if fglFinish is executed between the
execution of fglBegin and the corresponding execution of fglEnd.
MACHINE DEPENDENCIES
The SGIX_async and SGIX_async_pixel extensions are implemented only on
Octane2 VPro systems.
