PollableOutputStream

interface PollableOutputStream : Proxy(source)

GPollableOutputStream is implemented by class@Gio.OutputStreams that can be polled for readiness to write. This can be used when interfacing with a non-GIO API that expects UNIX-file-descriptor-style asynchronous I/O rather than GIO-style.

Some classes may implement GPollableOutputStream but have only certain instances of that class be pollable. If method@Gio.PollableOutputStream.can_poll returns false, then the behavior of other GPollableOutputStream methods is undefined.

Functions

canPoll

open fun canPoll(): Boolean

Checks if @stream is actually pollable. Some classes may implement #GPollableOutputStream but have only certain instances of that class be pollable. If this method returns false, then the behavior of other #GPollableOutputStream methods is undefined.

connect

open fun connect(connection: IoStream, proxyAddress: ProxyAddress, cancellable: Cancellable? = null): <Error class: unknown class><IoStream>

Given @connection to communicate with a proxy (eg, a #GSocketConnection that is connected to the proxy server), this does the necessary handshake to connect to @proxy_address, and if required, wraps the #GIOStream to handle proxy payload.

connectAsync

open fun connectAsync(connection: IoStream, proxyAddress: ProxyAddress, cancellable: Cancellable? = null, callback: AsyncReadyCallback?)

Asynchronous version of g_proxy_connect().

connectFinish

open fun connectFinish(result: AsyncResult): <Error class: unknown class><IoStream>

See g_proxy_connect().

createSource

open fun createSource(cancellable: Cancellable? = null): <Error class: unknown class>

Creates a #GSource that triggers when @stream can be written, or

isWritable

open fun isWritable(): Boolean

Checks if @stream can be written.

supportsHostname

open fun supportsHostname(): Boolean

Some proxy protocols expect to be passed a hostname, which they will resolve to an IP address themselves. Others, like SOCKS4, do not allow this. This function will return false if @proxy is implementing such a protocol. When false is returned, the caller should resolve the destination hostname first, and then pass a #GProxyAddress containing the stringified IP address to g_proxy_connect() or g_proxy_connect_async().
