OpenNtmsSessionW function (ntmsapi.h)

  • Article

[Removable Storage Manager is no longer available as of Windows 7 and Windows Server 2008 R2.]

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

Syntax

HANDLE OpenNtmsSessionW(
  [in] LPCWSTR lpServer,
  [in] LPCWSTR lpApplication,
       DWORD   dwOptions
);

Parameters

[in] lpServer

RSM server name. If this parameter is NULL, the current computer name is used.

[in] lpApplication

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.

Note

The ntmsapi.h header defines OpenNtmsSession as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
