CM_Free_Log_Conf_Ex function (cfgmgr32.h)

[Beginning with Windows 8 and Windows Server 2012, this function has been deprecated. Please use CM_Free_Log_Conf instead.]

The CM_Free_Log_Conf_Ex function removes a logical configuration and all associated resource descriptors from either a local or a remote machine.

Syntax

CMAPI CONFIGRET CM_Free_Log_Conf_Ex(
  [in]           LOG_CONF lcLogConfToBeFreed,
  [in]           ULONG    ulFlags,
  [in, optional] HMACHINE hMachine
);

Parameters

[in] lcLogConfToBeFreed

Caller-supplied handle to a logical configuration. This handle must have been previously obtained by calling one of the following functions:

CM_Add_Empty_Log_Conf

CM_Add_Empty_Log_Conf_Ex

CM_Get_First_Log_Conf

CM_Get_First_Log_Conf_Ex

CM_Get_Next_Log_Conf

CM_Get_Next_Log_Conf_Ex

[in] ulFlags

Not used, must be zero.

[in, optional] hMachine

Caller-supplied machine handle, obtained from a previous call to CM_Connect_Machine.

Note  Using this function to access remote machines is not supported beginning with Windows 8 and Windows Server 2012, as this functionality has been removed.
 

Return value

If the operation succeeds, the function returns CR_SUCCESS. Otherwise, it returns one of the CR_-prefixed error codes defined in Cfgmgr32.h.

Note  Starting with Windows 8, CM_Free_Log_Conf_Ex returns CR_CALL_NOT_IMPLEMENTED when used in a Wow64 scenario. To request information about the hardware resources on a local machine it is necessary implement an architecture-native version of the application using the hardware resource APIs. For example: An AMD64 application for AMD64 systems.
 

Remarks

Calling CM_Free_Log_Conf_Ex can cause the handles returned by CM_Get_First_Log_Conf_Ex and CM_Get_Next_Log_Conf_Ex to become invalid. Thus if you want to obtain logical configurations after calling CM_Free_Log_Conf_Ex, your code must call CM_Get_First_Log_Conf_Ex again and start at the first configuration.

Note that calling CM_Free_Log_Conf_Ex frees the configuration, but not the configuration's handle. To free the handle, call CM_Free_Log_Conf_Handle_Ex.

Callers of this function must have SeLoadDriverPrivilege. (Privileges are described in the Microsoft Windows SDK documentation.)

Functionality to access remote machines has been removed in Windows 8 and Windows Server 2012 and later operating systems thus you cannot access remote machines when running on these versions of Windows.
