js
clientWaitSync(sync, flags, timeout)
syncA WebGLSync object on which to wait on.
flags A GLbitfield specifying a bitwise combination of flags controlling the flushing behavior. May be gl.SYNC_FLUSH_COMMANDS_BIT.
timeout A GLint64 specifying a timeout (in nanoseconds) for which to wait for the sync object to become signaled. Must not be larger than gl.MAX_CLIENT_WAIT_TIMEOUT_WEBGL.
A GLenum indicating the sync object's status.
gl.ALREADY_SIGNALED: Indicates that the sync object was signaled when this method was called. gl.TIMEOUT_EXPIRED: Indicates that the timeout time passed and that the sync object did not become signaled. gl.CONDITION_SATISFIED: Indicates that the sync object was signaled before the timeout expired. gl.WAIT_FAILED: Indicates that an error occurred during the execution.js
const sync = gl.fenceSync(gl.SYNC_GPU_COMMANDS_COMPLETE, 0); const status = gl.clientWaitSync(sync, 0, 0);
