The LOGINOUT (LGI) routines are used by programmers implementing the requirements of site security administrators or third-party security software producers. The LGI routines do not deal strictly with callable routines that are internal to the OpenVMS system. The LOGINOUT callout routines (whose names begin with LGI$ICR_) are designed by site security administrators. The callback routines (whose names begin with LGI$ICB_) are invoked by the callout routines.
