Class NVSync

java.lang.Object

org.lwjgl.egl.NVSync

public class NVSync
extends java.lang.Object

Native bindings to the NV_sync extension.

This extension introduces the concept of "sync objects" into EGL. Sync objects are a synchronization primitive, representing events whose completion can be tested or waited upon. This extension borrows heavily from the GL_ARB_sync extension, and like that extension, introduces only a single type of sync object, the "fence sync object." Additional types of sync objects may be introduced in later extensions.

Fence sync objects have corresponding fences, which are inserted into client API command streams. A sync object can be queried for a given condition, such as completion of the corresponding fence. Fence completion allows applications to request a partial Finish of an API command stream, wherein all commands issued in a particular client API context will be forced to complete before control is returned to the calling thread.

Requires EGL 1.1.
