public Class KHREGLEvent

extends Object
Class Inheritance
Imports
javax.annotation.*, java.nio.*, org.lwjgl.system.*
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.

Field Summary

public static final int
CL_COMMAND_EGL_FENCE_SYNC_OBJECT_KHR

Returned by GetEventInfo when param_name is EVENT_COMMAND_TYPE.

public static final int
CL_INVALID_EGL_OBJECT_KHR

Returned by clCreateEventFromEGLSyncKHR if sync is not a valid EGLSyncKHR handle created with respect to EGLDisplay display.
