WebGL2RenderingContext.fenceSync

The WebGL2RenderingContext.fenceSync() method of the WebGL 2 API creates a new WebGLSync object and inserts it into the GL command stream.

Syntax

WebGLSync gl.fenceSync(condition, flags);

Parameters

condition

A GLenum specifying the condition that must be met to set the sync object's state to signaled. Must be gl.SYNC_GPU_COMMANDS_COMPLETE.

flags

A GLbitfield specifying a bitwise combination of flags controlling the behavior of the sync object. Must be 0 (exists for extensions only).

Return value

A WebGLSync object.

Examples

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

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