NAME    [Toc]    [Back]

     glDeleteAsyncMarkersSGIX -	delete markers for tracking asynchronous
     commands

C SPECIFICATION    [Toc]    [Back]

     void glDeleteAsyncMarkersSGIX( GLuint marker,
				    GLsizei range )

PARAMETERS    [Toc]    [Back]

     marker  Specifies the first marker	value to delete.

     range   Specifies the number of contiguous	marker values to delete.

DESCRIPTION    [Toc]    [Back]

     glDeleteAsyncMarkersSGIX 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.

     glDeleteAsyncMarkersSGIX 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 glGenAsyncMarkersSGIX 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 glDeleteAsyncMarkersSGIX 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    [Toc]    [Back]

     GL_INVALID_OPERATION is generated if glDeleteAsyncMarkersSGIX is executed
     between the execution of glBegin and the corresponding execution of
     glEnd.


MACHINE	DEPENDENCIES
     The SGIX_async and	SGIX_async_pixel extensions are	implemented only on
     Octane2 VPro systems.
