gNetworkAddressParse {RGtk2} | R Documentation

## gNetworkAddressParse

### 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`
