capture

Overview ¶

Package capture implements the main capture logic. It is meant to be re-usable and use only standard interfaces.

Example usage:

package main

// Importing fmt and time
import (
    "time"

    "github.com/yadutaf/ddump/pkg/capture"
)

func main() {
    // Prepare the capture file
    f, err := os.Create("/tmp/capture.pcap")
    if err != nil {
        panic(e)
    }

    // Start the capture in the background
    done := make(chan struct{})
    go func() {
        err := capture.Capture("eth0", "tcp port 80")
        if err != nil {
              panic(e)
        }
        close(done)
    }

    // Stop the capture after 3s, or early exit
    select {
    case <-time.After(3 * time.Second):
    case <-done:
    }

    // Close the writer
    f.Close()

    // Wait until done
    <-done
}
