# eglWaitNative

complete native execution prior to subsequent GL rendering calls

## C Specification

`EGLBoolean eglWaitNative(` | EGLint engine`)`

## Parameters

`engine`

  Specifies a particular marking engine to be waited on. Must be `EGL_CORE_NATIVE_ENGINE`.

## Description

Native rendering calls made prior to `eglWaitNative` are guaranteed to be executed before GL rendering calls made after `eglWaitNative`.

`eglWaitNative` is ignored if there is no current EGL rendering context.

## Errors

`EGL_BAD_PARAMETER` is generated if `engine` is not a recognized marking engine.

`EGL_BAD_CURRENT_SURFACE` is generated if the surface associated with the current context has a native window or pixmap, and that window or pixmap is no longer valid.
