Routine Description:
|
|
|
|
This function is used to connect to the NT Session Manager
|
|
|
|
Arguments:
|
|
|
|
SbApiPortName - Supplies the name of the sub system's session management
|
|
API port (for Sb APIs). That the session manager is to connect with.
|
|
|
|
SbApiPort - Supplies a port handle to the connection port where the
|
|
subsystem's session management (Sb) APIs are exported.
|
|
|
|
SbImageType - Supplies the image type that the connecting subsystem
|
|
serves.
|
|
|
|
SmApiPort - Returns the communication port which is connected to the
|
|
session manager and over which Sm APIs may be made.
|
|
|
|
Return Value:
|
|
|
|
TBD.
