set_callback_indirect

Description:

public void set_callback_indirect (void* callback_data, SourceCallbackFuncs callback_funcs)

Sets the callback function storing the data as a reference counted callback ‘object’.

This is used internally. Note that calling [method@GLib.Source.set_callback_indirect] assumes an initial reference count on callback_data, and thus `callback_funcs->unref` will eventually be called once more than `callback_funcs->ref`.

It is safe to call this function multiple times on a source which has already been attached to a context. The changes will take effect for the next time the source is dispatched after this call returns.

Parameters:

this	the source
callback_data	pointer to callback data ‘object’
callback_funcs	functions for reference counting `callback_data` and getting the callback and data
