boolean share_lock(number share_handle[, bool blocking=false])

class Main {
	function Main() {
		var ctx=share_open(123);
		echo ctx;
		share_lock(ctx);
		for (var i=0;i<200000;i++) {
			share_set(ctx,""+i);
		}
		echo "done lock";
		echo "SH:"+share_unlock(ctx)+"\n";
		echo "SH:"+share_unlock(ctx)+"\n";
		echo share_get(ctx);
		echo "\n";
		echo typeof this;
		while (1) {
			echo ""+share_link_count(ctx)+"\r";
		}
	}
}

Returns:
