Function
GLibio_create_watch
Declaration [src]
GSource*
g_io_create_watch (
GIOChannel* channel,
GIOCondition condition
)
Description [src]
Creates a GSource
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 GSource
should be added with
g_source_set_callback(), but it has type GIOFunc
(not GSourceFunc
).
g_io_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 GSource
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.
