facilities provided by the NT Session manager.
|
|
|
|
This function closes all handles passed to it.
|
|
|
|
Arguments:
|
|
|
|
SmApiPort - Supplies a handle to a communications port connected
|
|
to the Session Manager.
|
|
|
|
ProcessInformation - Supplies a process description as returned
|
|
by RtlCreateUserProcess.
|
|
|
|
DebugFlag - Supplies and optional parameter which if set indicates
|
|
that the caller wants to debug this process and act as its
|
|
debug user interface.
|
