Function

GioNetworkAddressparse

since: 2.22

Declaration

GSocketConnectable*
g_network_address_parse (
  const gchar* host_and_port,
  guint16 default_port,
  GError** error
)

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.

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.

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 override if necessary) and default_port is expected to be provided by the application.

(The port component of host_and_port can also be specified as a service name rather than as a numeric port, but this functionality is deprecated, because it depends on the contents of /etc/services, which is generally quite sparse on platforms other than Linux.)

Available since: 2.22

Parameters

host_and_port

Type: const gchar*

The hostname and optionally a port.

The data is owned by the caller of the function.

The value is a NUL terminated UTF-8 string.

default_port

Type: guint16

The default port if not in host_and_port.

error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.

If the return location is not NULL, then you must initialize it to a NULL GError*.

The argument will left initialized to NULL by the function if there are no errors.

In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: GNetworkAddress

The new GNetworkAddress, or NULL on error.

The caller of the function takes ownership of the data, and is responsible for freeing it.
