glGenAsyncMarkersSGIX - reserve markers for tracking asynchronous
GLuint glGenAsyncMarkersSGIX( GLsizei range )
range Specifies the number of contiguous marker values to reserve.
glGenAsyncMarkersSGIX 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
A marker for asynchronous commands is "in use" if it is the current value
of GL_ASYNC_MARKER_SGIX, or if it is associated with any asynchronous
command that has been issued but has not been queried using
glFinishAsyncSGIX or glPollAsyncSGIX.
glGenAsyncMarkersSGIX returns an integer n such that the markers n, n+1,
n+2, ..., n+s-1 are not previously reserved or in use, where s is the
value of range. glGenAsyncMarkersSGIX also records that each of the
markers in the returned range is reserved.
Note that the marker name space is never shared across contexts, as the
name spaces for texture objects and display lists may be.
GL_INVALID_OPERATION is generated if glGenAsyncMarkersSGIX is executed
between the execution of glBegin and the corresponding execution of
The SGIX_async and SGIX_async_pixel extensions are implemented only on
Octane2 VPro systems.
