ioAddWatch
fun ioAddWatch(channel: IOChannel, priority: Int, condition: IOCondition, func: IOFunc): <Error class: unknown class>
Adds the #GIOChannel into the default main loop context with the given priority.
This internally creates a main loop source using g_io_create_watch() and attaches it to the main loop context with g_source_attach(). You can do these steps manually if you need greater control.
Return
the event source id
Parameters
channel
a #GIOChannel
priority
the priority of the #GIOChannel source
condition
the condition to watch for
func
the function to call when the condition is satisfied
