WebGL2RenderingContext.deleteSync()

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The WebGL2RenderingContext.deleteSync() method of the WebGL 2 API deletes a given WebGLSync object.

Syntax

void gl.deleteSync(sync);

Parameters

sync
A WebGLSync object to delete.

Return value

None.

Examples

gl must be a WebGL2RenderingContext. WebGLSync objects are not available in WebGL 1.

var sync = gl.fenceSync(gl.SYNC_GPU_COMMANDS_COMPLETE, 0);

// ...

gl.deleteSync(sync);
