IOSource


Description:

[ CCode ( cname = "g_io_create_watch" ) ]
public IOSource (IOChannel channel, IOCondition condition)

Creates a SignalSource that's dispatched when condition is met for the given channel.

For example, if condition is g_io_in, the source will be dispatched when there's data available for reading.

The callback function invoked by the SignalSource should be added with set_callback, but it has type IOFunc (not SourceFunc).

add_watch is a simpler interface to this same functionality, for the case where you want to add the source to the default main loop context at the default priority.

On Windows, polling a SignalSource created to watch a channel for a socket puts the socket in non-blocking mode. This is a side-effect of the implementation and unavoidable.

Parameters:

channel

a IOChannel to watch

condition

conditions to watch for

Returns:

a new SignalSource
