Detailed Description

Input I/O notification.

Basically this is a duplicate of the GDK input facilities, without the features gtkg does not use.

The intent here is to break the GDK dependency but retain the same behavior, to avoid disturbing too much of the existing code.

guint inputevt_add (  gint  fd, inputevt_cond_t  cond, inputevt_handler_t  handler, gpointer  data )

This emulates the GDK input interface. A replacement for gdk_input_add(). Behaves exactly the same, except destroy notification has been removed (since gtkg does not use it).

guint inputevt_add_source (  inputevt_relay_t *  relay  )  [static]

guint inputevt_add_source_with_glib (  inputevt_relay_t *  relay  )  [static]

void inputevt_close (  void   )

Performs module cleanup.

const gchar* inputevt_cond_to_string (  inputevt_cond_t  cond  )

gboolean inputevt_dispatch (  GIOChannel *  source, GIOCondition  condition, gpointer  data )  [static]

Relays the event to the registered handler function. The input condition flags are properly mapped before being passed on.

void inputevt_init (  void   )

Performs module initialization.

void inputevt_relay_destroy (  gpointer  data  )  [static]

Frees the relay structure when its time comes.
