Module Name:
|
|
|
|
SrvList.c
|
|
|
|
Abstract:
|
|
|
|
The server component of Remote. This module
|
|
implements three lists of REMOTE_CLIENT structures,
|
|
for handshaking, connected, and closing clients.
|
|
To simplify the interface items always progress
|
|
through the three lists in order, with list node
|
|
memory being freed as it is removed from the
|
|
closing list.
