Various parts of the library allow callback watches to be placed on particular events. When the event occurs, the callback function will be invoked. These watches are represented by a IrmoCallback object.

Typedef Documentation

typedef struct _IrmoCallback IrmoCallback

Callback object. When a new callback watch is created, an IrmoCallback object is returned representing the watch. The watch can be unset with irmo_callback_unset

typedef void(* IrmoCallbackCallback)(IrmoCallback *callback, void *user_data)

Function Documentation

void irmo_callback_unset (  IrmoCallback *  callback  )

Unset a callback watch. Unsets a watch on a callback object. Parameters: callback  The callback to destroy.

IrmoCallback* irmo_callback_watch_destroy (  IrmoCallback *  callback, IrmoCallbackCallback  func, void *  user_data )

Set a callback for when a IrmoCallback is destroyed. This invokes a callback when a callback object is destroyed, either from being explicitely unset or if the object it is watching is destroyed. This is mostly useful when writing language bindings so that the language can know when to free a callback context. Parameters: callback  The callback to watch func  Function to invoke user_data  Extra data to pass to the function. Returns: A new callback object representing the watch.
