gflush(3G)                                                          gflush(3G)


NAME
     gflush - flushs the remote GL client buffer

C SPECIFICATION
     void gflush()

PARAMETERS
     none

DESCRIPTION
     gflush guarantees that GL graphics calls are flushed to the display
     hardware.

SEE ALSO
     finish

NOTE
     The GL client buffers the output from most graphics routines for
     efficient block transfer to the server. gflush sends all buffered but
     untransmitted graphics data to the server. Certain graphics routines,
     notably those that return values, also flush the client buffer when they
     execute.  On older machines gflush had an effect only when rendering
     across the network.  Modern machines queue graphics commands even when
     rendering locally, however, so gflush should be called for both local and
     remote rendering applications.
