Virtual Method

GioProxyResolverlookup

since: 2.26

Declaration [src]

gchar**
lookup (
  GProxyResolver* resolver,
  const gchar* uri,
  GCancellable* cancellable,
  GError** error
)

Description [src]

Looks into the system proxy configuration to determine what proxy, if any, to use to connect to uri. The returned proxy URIs are of the form <protocol>://[user[:password]@]host[:port] or direct://, where <protocol> could be http, rtsp, socks or other proxying protocol.

If you don’t know what network protocol is being used on the socket, you should use none as the URI protocol. In this case, the resolver might still return a generic proxy type (such as SOCKS), but would not return protocol-specific proxy types (such as http).

direct:// is used when no proxy is needed. Direct connection should not be attempted unless it is part of the returned array of proxies.

Available since: 2.26

Parameters

uri

Type: const gchar*

A URI representing the destination to connect to.

The data is owned by the caller of the method.

The value is a NUL terminated UTF-8 string.

cancellable

Type: GCancellable

A GCancellable, or NULL.

The argument can be NULL.

The data is owned by the caller of the method.

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 be left initialized to NULL by the virtual 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: An array of utf8

A NULL-terminated array of proxy URIs. Must be freed with g_strfreev().

The array is NULL-terminated.

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

Each element is a NUL terminated UTF-8 string.
