Detailed Description

GPollableOutputStreamInterface: @g_iface: The parent interface. @can_poll: Checks if the GPollableOutputStream instance is actually pollable @is_writable: Checks if the stream is writable @create_source: Creates a GSource to poll the stream @write_nonblocking: Does a non-blocking write or returns G_IO_ERROR_WOULD_BLOCK @writev_nonblocking: Does a vectored non-blocking write, or returns G_POLLABLE_RETURN_WOULD_BLOCK

The interface for pollable output streams.

The default implementation of @can_poll always returns TRUE.

The default implementation of @write_nonblocking calls g_pollable_output_stream_is_writable(), and then calls g_output_stream_write() if it returns TRUE. This means you only need to override it if it is possible that your @is_writable implementation may return TRUE when the stream is not actually writable.

The default implementation of @writev_nonblocking calls g_pollable_output_stream_write_nonblocking() for each vector, and converts its return value and error (if set) to a GPollableReturn. You should override this where possible to avoid having to allocate a #GError to return G_IO_ERROR_WOULD_BLOCK.
