public Class KHRGLEvent

extends Object
Class Inheritance
Imports
javax.annotation.*, java.nio.*, org.lwjgl.system.*
Native bindings to the khr_gl_event extension.

This extension allows creating OpenCL event objects linked to OpenGL fence sync objects, potentially improving efficiency of sharing images and buffers between the two APIs. The companion GL_ARB_cl_event extension provides the complementary functionality of creating an OpenGL sync object from an OpenCL event object.

In addition, this extension modifies the behavior of EnqueueAcquireGLObjects and EnqueueReleaseGLObjects to implicitly guarantee synchronization with an OpenGL context bound in the same thread as the OpenCL context.

public static long clCreateEventFromGLsyncKHR(long context, long sync, IntBuffer errcode_ret)

Creates an OpenCL event object from an OpenGL fence sync object.

Parameters
context:long
