+# 18.6 函数
+
+    如何使用内建函数recover停止panic过程（参考13.3小节）：
+    
+```go
+func protect(g func()) {
+    defer func() {
+        log.Println("done")
+        // Println executes normally even if there is a panic
+        if x := recover(); x != nil {
+            log.Printf("run time panic: %v", x)
+        }
+    }()
+    log.Println("start")
+    g()
+}
+```
