file,_ := os.Create("text.txt") buf := bytes.NewBufferString("hello world") buf.WriteTo(file) //或者使用写入,fmt.Fprintf(file,buf.String()) }复制代码 四、读出缓冲器 1、Read方法,给Read方法一个容器,读完后p就满了,缓冲器相应的减少。 // func (b *Buffer) Read(p []byte)(n int,e...
Println(string(line)) } As you probably already know, We just read the file so far, we did actually solve the problem that we had with the gigantic lines. we ignore the second parameter that we gave from the ReadLine function and that one is what we exactly need to solve our problem...

通过阅读README知道,go1.txt可以通过go tool api命令生成。而通过go1.txt可以做成编辑器的api自动提示,比如Vim:VimForGo next.txt是一些将来可能加入的API 二、Go基本工具(cmd) 1、include目录 该目录包含以下文件(文件夹) ar.h bio.h bootexec.h fmt.h libc.h mach.h plan9 u.h ureg_amd64.h ureg...
