Package org.lwjgl.opencl

Class KHREGLEvent

java.lang.Object

org.lwjgl.opencl.KHREGLEvent

public class KHREGLEvent
extends java.lang.Object

Native bindings to the khr_egl_event extension.

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

public static long clCreateEventFromEGLSyncKHR(long context,
                                               long sync,

                                               java.nio.IntBuffer errcode_ret)

Creates a linked event object.

Parameters:

context - a valid OpenCL context

sync - the name of a sync object of type EGL15.EGL_SYNC_FENCE created with respect to EGLDisplay display.

display - an EGLDisplay

errcode_ret - will return an appropriate error code. If errcode_ret is NULL, no error code is returned.
