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.

Method Detail

clCreateEventFromEGLSyncKHR

public static long clCreateEventFromEGLSyncKHR(long context,
                                               long sync,
                                               long display,
                                               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.
