# listenbuffer
|
||
|
|
||
|
listenbuffer uses the kernel's listening backlog functionality to queue
|
||
|
connections, allowing applications to start listening immediately and handle
|
||
|
connections later. This is signaled by closing the activation channel passed to
|
||
|
the constructor.
|
||
|
|
||
|
The maximum amount of queued connections depends on the configuration of your
|
||
|
kernel (typically called SOMAXXCON) and cannot be configured in Go with the
|
||
|
net package. See `src/net/sock_platform.go` in the Go tree or consult your
|
||
|
kernel's manual.
|
||
|
|
||
|
activator := make(chan struct{})
|
||
|
buffer, err := NewListenBuffer("tcp", "localhost:4000", activator)
|
||
|
if err != nil {
|
||
|
panic(err)
|
||
|
}
|
||
|
|
||
|
// will block until activator has been closed or is sent an event
|
||
|
client, err := buffer.Accept()
|
||
|
|
||
|
Somewhere else in your application once it's been booted:
|
||
|
|
||
|
close(activator)
|
||
|
|
||
|
`buffer.Accept()` will return the first client in the kernel listening queue, or
|
||
|
continue to block until a client connects or an error occurs.
