# 18.6 函数
|
||
|
||
如何使用内建函数 `recover()` 终止 `panic()` 过程（参考[章节 13.3](13.3.md)）：
|
||
|
||
```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()
|
||
}
|
||
```
