This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
GLenum gl.clientWaitSync(sync, flags, timeout);
WebGLSyncobject on which to wait on.
GLbitfieldspecifying a bitwise combination of flags controlling the flushing behavior. May be
GLint64specifying a timeout (in nanoseconds) for which to wait for the sync object to become signaled. Must not be larger than
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
timeouttime passed and that the sync object did not become signaled.
gl.CONDITION_SATISFIED: Indicates that the sync object was signaled before the
gl.WAIT_FAILED: Indicates that an error occurred during the execution.
