// -=- TcpSocket.h - base-class for TCP stream sockets.
|
|
// This header also defines the TcpListener class, used
|
|
// to listen for incoming socket connections over TCP
|
|
//
|
|
// NB: Any file descriptors created by the TcpSocket or
|
|
// TcpListener classes are close-on-exec if the OS supports
|
|
// it. TcpSockets initialised with a caller-supplied fd
|
|
// are NOT set to close-on-exec.
