### List SMB Share Names in Go

Source: https://github.com/hirochachacha/go-smb2/blob/master/README.md

This Go example demonstrates how to connect to an SMB server, authenticate using NTLM, and list all available share names. It establishes a TCP connection, dials an SMB2 session, and then calls `ListSharenames()` to retrieve the names.

```Go
package main

import (
	"fmt"
	"net"

	"github.com/hirochachacha/go-smb2"
)

func main() {
	conn, err := net.Dial("tcp", "SERVERNAME:445")
	if err != nil {
		panic(err)
	}
	defer conn.Close()

	d := &smb2.Dialer{
		Initiator: &smb2.NTLMInitiator{
			User:     "USERNAME",
			Password: "PASSWORD",
		},
	}

	s, err := d.Dial(conn)
	if err != nil {
		panic(err)
	}
	defer s.Logoff()

	names, err := s.ListSharenames()
	if err != nil {
		panic(err)
	}

	for _, name := range names {
		fmt.Println(name)
	}
}
```

### Glob and Walk SMB Directory with Go's io/fs Interface

Source: https://github.com/hirochachacha/go-smb2/blob/master/README.md

This Go example demonstrates how to use the standard `io/fs` package functions, `iofs.Glob` and `iofs.WalkDir`, with an SMB file system. It connects to an SMB server, mounts a share, and then uses the `DirFS` method to expose the SMB share as an `io/fs.FS` interface for directory traversal and pattern matching.

```Go
package main

import (
	"fmt"
	"net"
	iofs "io/fs"

	"github.com/hirochachacha/go-smb2"
)

func main() {
	conn, err := net.Dial("tcp", "SERVERNAME:445")
	if err != nil {
		panic(err)
	}
	defer conn.Close()

	d := &smb2.Dialer{
		Initiator: &smb2.NTLMInitiator{
			User:     "USERNAME",
			Password: "PASSWORD",
		},
	}

	s, err := d.Dial(conn)
	if err != nil {
		panic(err)
	}
	defer s.Logoff()

	fs, err := s.Mount("SHARENAME")
	if err != nil {
		panic(err)
	}
	defer fs.Umount()

	matches, err := iofs.Glob(fs.DirFS("."), "*")
	if err != nil {
		panic(err)
	}
	for _, match := range matches {
		fmt.Println(match)
	}

	err = iofs.WalkDir(fs.DirFS("."), ".", func(path string, d iofs.DirEntry, err error) error {
		fmt.Println(path, d, err)

		return nil
	})
	if err != nil {
		panic(err)
	}
}
```

### Handle SMB Error Types in Go

Source: https://github.com/hirochachacha/go-smb2/blob/master/README.md

This Go example shows how to check for specific SMB error types using `os.IsNotExist`, `os.IsPermission`, and `os.IsTimeout`. It attempts to open a non-existent file, write to a read-only file, and perform an operation with a timeout, demonstrating how to identify common error conditions.

```Go
package main

import (
	"context"
	"fmt"
	"net"
	"os"

	"github.com/hirochachacha/go-smb2"
)

func main() {
	conn, err := net.Dial("tcp", "SERVERNAME:445")
	if err != nil {
		panic(err)
	}
	defer conn.Close()

	d := &smb2.Dialer{
		Initiator: &smb2.NTLMInitiator{
			User:     "USERNAME",
			Password: "PASSWORD",
		},
	}

	s, err := d.Dial(conn)
	if err != nil {
		panic(err)
	}
	defer s.Logoff()

	fs, err := s.Mount("SHARENAME")
	if err != nil {
		panic(err)
	}
	defer fs.Umount()

	_, err = fs.Open("notExist.txt")

	fmt.Println(os.IsNotExist(err)) // true
	fmt.Println(os.IsExist(err))    // false

	fs.WriteFile("hello2.txt", []byte("test"), 0444)
	err = fs.WriteFile("hello2.txt", []byte("test2"), 0444)
	fmt.Println(os.IsPermission(err)) // true

	ctx, cancel := context.WithTimeout(context.Background(), 0)
	defer cancel()

	_, err = fs.WithContext(ctx).Open("hello.txt")

	fmt.Println(os.IsTimeout(err)) // true
}
```

### Perform SMB File Operations in Go

Source: https://github.com/hirochachacha/go-smb2/blob/master/README.md

This Go example illustrates how to perform basic file manipulation (create, write, read, remove) on an SMB share. It connects to the server, mounts a specified share, creates a file, writes content, seeks to the beginning, reads the content, and then removes the file.

```Go
package main

import (
	"io"
	"io/ioutil"
	"net"

	"github.com/hirochachacha/go-smb2"
)

func main() {
	conn, err := net.Dial("tcp", "SERVERNAME:445")
	if err != nil {
		panic(err)
	}
	defer conn.Close()

	d := &smb2.Dialer{
		Initiator: &smb2.NTLMInitiator{
			User:     "USERNAME",
			Password: "PASSWORD",
		},
	}

	s, err := d.Dial(conn)
	if err != nil {
		panic(err)
	}
	defer s.Logoff()

	fs, err := s.Mount("SHARENAME")
	if err != nil {
		panic(err)
	}
	defer fs.Umount()

	f, err := fs.Create("hello.txt")
	if err != nil {
		panic(err)
	}
	defer fs.Remove("hello.txt")
	defer f.Close()

	_, err = f.Write([]byte("Hello world!"))
	if err != nil {
		panic(err)
	}

	_, err = f.Seek(0, io.SeekStart)
	if err != nil {
		panic(err)
	}

	bs, err := ioutil.ReadAll(f)
	if err != nil {
		panic(err)
	}

	fmt.Println(string(bs))
}
```
