Detailed Description

Regist and execute callback functions.

This file contains functions for handling callback functions. User should use callback_add() (and callback_add_adin() for A/D-in related callbacks) to regist user function to the callback repository. Then, Julius will call the registered functions at apropriate timimg while search.

More than one function can be assigned to a callback, in which case all functions will be called in turn.
