gNetworkAddressParse: gNetworkAddressParse

In RGtk2: R Bindings for Gtk 2.8.0 and Above

Description

Creates a new GSocketConnectable for connecting to the given hostname and port. May fail and return NULL in case parsing host.and.port fails.

Usage

gNetworkAddressParse(host.and.port, default.port, .errwarn = TRUE)

Arguments

host.and.port	the hostname and optionally a port
default.port	the default port if not in host.and.port
.errwarn	Whether to issue a warning on error or fail silently

Details

host.and.port may be in any of a number of recognised formats: an IPv6 address, an IPv4 address, or a domain name (in which case a DNS lookup is performed). Quoting with [] is supported for all address types. A port override may be specified in the usual way with a colon. Ports may be given as decimal numbers or symbolic names (in which case an /etc/services lookup is performed).

If no port is specified in host.and.port then default.port will be used as the port number to connect to.

In general, host.and.port is expected to be provided by the user (allowing them to give the hostname, and a port overide if necessary) and default.port is expected to be provided by the application. Since 2.22

Value

A list containing the following elements:

retval	[GSocketConnectable] the new GNetworkAddress, or NULL on error
error	a pointer to a GError, or NULL
