Copyright (c) 1991 Microsoft Corporation
Module Name:
ApiChDev.c
Abstract:
This module contains individual API handlers for the NetCharDev
and NetCharDevQ APIs. Supported APIs are NetCharDevControl,
NetCharDevEnum, NetCharDevGetInfo, NetCharDevQEnum, NetCharDevQGetInfo,
NetCharDevQPurge, NetCharDevQPurgeSelf, and NetCharDevQSetInfo.
SUPPORTED: NetCharDevControl, NetCharDevEnum, NetCharDevGetInfo,
NetCharDevQEnum, NetCharDevQGetInfo, NetCharDevQPurge,
NetCharDevQPurgeSelf, NetCharDevQSetInfo.
!!! Remove handlers for unsupported APIs when done.
