gSocketBind: gSocketBind

In RGtk2: R Bindings for Gtk 2.8.0 and Above

Description

When a socket is created it is attached to an address family, but it doesn't have an address in this family. gSocketBind assigns the address (sometimes called name) of the socket.

Usage

gSocketBind(object, address, allow.reuse, .errwarn = TRUE)

Arguments

object	a GSocket.
address	a GSocketAddress specifying the local address.
allow.reuse	whether to allow reusing this address
.errwarn	Whether to issue a warning on error or fail silently

Details

It is generally required to bind to a local address before you can receive connections. (See gSocketListen and gSocketAccept ). In certain situations, you may also want to bind a socket that will be used to initiate connections, though this is not normally required. allow.reuse should be TRUE for server sockets (sockets that you will eventually call gSocketAccept on), and FALSE for client sockets. (Specifically, if it is TRUE, then gSocketBind will set the SO_REUSEADDR flag on the socket, allowing it to bind address even if that address was previously used by another socket that has not yet been fully cleaned-up by the kernel. Failing to set this flag on a server socket may cause the bind call to return G_IO_ERROR_ADDRESS_IN_USE if the server program is stopped and then immediately restarted.) Since 2.22

Value

A list containing the following elements:

retval	[logical] TRUE on success, FALSE on error.
error	GError for error reporting, or NULL to ignore.
