The OpenNtmsSession function sets up a session with a RSM server.

Syntax

HANDLE OpenNtmsSession(
  __in  LPCTSTR lpServer,
  __in  LPCTSTR lpApplication,
  DWORD dwOptions
);

Parameters

lpServer [in]
RSM server name. If this parameter is NULL, the current computer name is used.
lpApplication [in]
Unique character string that identifies the application. This name identifies resources and operator requests. This parameter is optional and may be NULL.
dwOptions
Reserved; must be zero.

Return Value

If OpenNtmsSession succeeds, it returns a handle that uniquely identifies this session. If the function fails, it returns INVALID_HANDLE_VALUE. To retrieve more information, call the GetLastError function. This function can return one of the following values.

Value	Meaning
ERROR_INVALID_COMPUTERNAME	The computer name format that was specified was not in a valid format.
ERROR_INVALID_PARAMETER	One of the parameter values was not valid.
ERROR_NO_NETWORK	The network is not started or not available.
ERROR_NOT_CONNECTED	Unable to connect to the RSM service.
ERROR_NOT_READY	RSM service has not started. The application should wait and retry.
ERROR_SUCCESS	The function was successful.
INVALID_HANDLE_VALUE	RSM cannot open a session.
RPC_S_NO_INTERFACES	The service is using an older version of RSM than your application.

Remarks

The OpenNtmsSession function returns a session handle used with other RSM functions, establishes a connection with the RSM database, and initializes the RSM subsystem for the application.

When OpenNtmsSession returns, the application can perform RSM operations.

Sessions are thread-safe but cannot be passed among processes.
