fglDeleteAsyncMarkersSGIX(3G) OpenGL Reference 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.
