Source.setCallbackIndirect

void setCallbackIndirect(void * callbackData, glib.types.SourceCallbackFuncs callbackFuncs)

Sets the callback function storing the data as a refcounted callback "object". This is used internally. Note that calling [glib.source.Source.setCallbackIndirect] 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

callbackDatapointer to callback data "object"
callbackFuncsfunctions for reference counting callback_data and getting the callback and data
