golang bufio in object

I'm fairly new to Golang; previously used Python.

I am having difficult time to apply bufio in the object.

type fout struct {
	filename string
	fo File 
	bfo Writer

}
func (a *fout) init() {
	a.fo,_:=os.Open(a.filename)
	a.bfo:=bufio.NewWriter(fo)
}

Basically, I like to create objects; each will have it's filename, and bufio will be used.

Can anyone help me please?

Thank you

Few things in the code sample:

• Every use of a name from another package needs to be prefixed with the package name--so fo File has to be fo *os.File.
• You normally declare *bufio.Writer and *os.File as pointers (see the bufio and file docs at http://golang.org/pkg)
• You want plain =, not :=, for assigning to attributes like a.fo and a.bfo.
• Don't throw away errors, particularly if you're used to exceptions, or you'll have impossible-to-debug problems. (For a trivial script for learning you can if err != nil { panic(err) }, but for real use, you almost always want to return them.)

It could also help to review the tour, pick up some tricks/advice from the various talks and blog posts, maybe walk through Go By Example (I admit I haven't persionally used it but sounds like it could be useful when getting started), look at some open-source Go code (projects on Github, the stdlib, anything), and run through the surprisingly readable spec once you're at the level where you want to know how the language really works.
