fglDeleteAsyncMarkersSGIX(3G)

NAME
     fglDeleteAsyncMarkersSGIX - delete markers for tracking asynchronous
     commands


FORTRAN SPECIFICATION
     SUBROUTINE fglDeleteAsyncMarkersSGIX( INTEGER*4 marker,
                                           INTEGER*4 range )


PARAMETERS
     marker  Specifies the first marker value to delete.

     range   Specifies the number of contiguous marker values to delete.

DESCRIPTION
     fglDeleteAsyncMarkersSGIX is part of the SGIX_async extension.  This
     extension provides a framework within which particular sets of OpenGL
     commands can become "asynchronous" via specific further OpenGL
     extensions.  Currently the SGIX_async_pixel extension is the only such
     defined extension.

     fglDeleteAsyncMarkersSGIX records that each of the markers in the range
     n, n+1, n+2, ..., n+s-1 is no longer reserved, where n is the value of
     marker and s is the value of range.  (Markers are reserved via the use of
     the fglGenAsyncMarkersSGIX command.)  It is not an error if some of the
     markers in the range are not reserved or are currently in use, but a
     marker that is in use will remain so even if fglDeleteAsyncMarkersSGIX is
     called.

     Note that the marker name space is never shared across contexts, as the
     name spaces for texture objects and display lists may be.

ERRORS
     GL_INVALID_OPERATION is generated if fglDeleteAsyncMarkersSGIX 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.
