WebGL2RenderingContext: waitSync() method

Available in workers

The WebGL2RenderingContext.waitSync() method of the WebGL 2 API returns immediately, but waits on the GL server until the given WebGLSync object is signaled.

The method is a no-op in the absence of the possibility of synchronizing between multiple GL contexts.

Syntax

waitSync(sync, flags, timeout)

Parameters

sync
- : A WebGLSync object on which to wait on.
flags
- : A GLbitfield specifying a bitwise combination of flags controlling the flushing behavior. Must be 0 (exists for extensions only).
timeout
- : A GLint64 specifying a timeout the server should wait before continuing. Must be gl.TIMEOUT_IGNORED.

Return value

None (undefined).

Examples

const sync = gl.fenceSync(gl.SYNC_GPU_COMMANDS_COMPLETE, 0);
gl.waitSync(sync, 0, gl.TIMEOUT_IGNORED);
