| <h2>Description</h2> |
| <p> |
| <code class="function">eglDestroySync</code> is used to destroy an |
| existing sync object. |
| </p> |
| <p> |
| If any <code class="function">eglClientWaitSync</code> or |
| <code class="function">eglWaitSync</code> commands are blocking on |
| <em class="parameter"><code>sync</code></em> when |
| <code class="function">eglDestroySync</code> is called, |
| <em class="parameter"><code>sync</code></em> is flagged for deletion and will be |
| deleted when the associated fence command or OpenCL event object |
| has completed, and <em class="parameter"><code>sync</code></em> is no longer |
| blocking any such <code class="function">egl*WaitSync</code> command. |
| Otherwise, the sync object is destroyed immediately. |
| </p> |
| <p> |
| If no errors are generated, <code class="constant">EGL_TRUE</code> is |
| returned, and <em class="parameter"><code>sync</code></em> will no longer be the |
| handle of a valid sync object. |
| </p> |
| </div> |
| <div class="refsect1" id="errors"> |
| <h2>Errors</h2> |
| <p> |
| On failure, <code class="function">eglDestroySync</code> returns |
| <code class="constant">EGL_FALSE</code>. |
| </p> |
| <p> |
| If <em class="parameter"><code>sync</code></em> is not a valid sync object for |
| <em class="parameter"><code>display</code></em>, <code class="constant">EGL_FALSE</code> |
| is returned and an <code class="constant">EGL_BAD_PARAMETER</code> error |
| is generated. |
| </p> |
| <p> |
| If <em class="parameter"><code>display</code></em> does not match the display |
| passed to <code class="function">eglCreateSync</code> when |
| <em class="parameter"><code>sync</code></em> was created, the behaviour is |
| undefined. |
| </p> |
| </div> |
| <div class="refsect1" id="notes"> |
| <h2>Notes</h2> |
| <p> |
| <code class="function">eglDestroySync</code> is available only if the EGL |
| version is 1.5 or greater. |
