ZSocket is a library that wraps the linux zero-copy socket syscall to create a ring buffer in a memory mapped file. It also contains some utility functions and types to help with a handful of layer 2 and layer 3 types. It is a lot like libcap, except it has easy to understand facilities for Writing to and interface. Example
The following program will print out any recognized nettypes, going down to layer 3.
package main
import "github.com/nathanjsweet/zsocket"
func main() {
zs, err := zsocket.NewZSocket(15, zsocket.ENABLE_RX|zsocket.ENABLE_TX, 256, nettypes.All)
if err != nil {
panic(err)
}
zs2.Listen(func(f *nettypes.Frame, frameLen uint32) {
fmt.Printf(f.String(frameLen, 0))
})
}The ZSocket type has methods for Writing frames to the ring buffer and flushing them.
