# bpf/files [](https://godoc.org/github.com/hyperized/bpf/file)
Utility library for bpf files.
Useful for BSD: Darwin, Dragonfly, FreeBSD, NetBSD & OpenBSD
## Files
Example implementation:
```go
package main
import (
"github.com/hyperized/bpf/file"
"log"
)
func main() {
// Use logging, off by default
bpf, err := file.GetBpfDevice(true)
defer func() {
if err := bpf.Close(); err != nil {
log.Printf(err.Error())
}
}()
// Showing off methods available
if bpf != nil {
log.Println(bpf.File())
log.Println(bpf.Path())
log.Println(bpf.FileDescriptor())
} else {
log.Println(err)
}
// Open new bpf device, this will be a new one, since the previous one is already open
bpf2, err := file.GetBpfDevice(true)
defer func() {
if err := bpf2.Close(); err != nil {
log.Printf(err.Error())
}
}()
log.Println(bpf2.Path())
}
```
