ClfsMgmtSetLogFileSizeAsClient function (wdm.h)

  • Article

The ClfsMgmtSetLogFileSizeAsClient routine sets the log file size by adding containers to a client log or deleting containers from a client log.

Syntax

CLFSUSER_API NTSTATUS ClfsMgmtSetLogFileSizeAsClient(
  [in]            PLOG_FILE_OBJECT                     LogFile,
  [in, optional]  PCLFS_MGMT_CLIENT                    ClientCookie,
  [in]            PULONGLONG                           NewSizeInContainers,
  [out, optional] PULONGLONG                           ResultingSizeInContainers,
  [in, optional]  PCLFS_SET_LOG_SIZE_COMPLETE_CALLBACK CompletionRoutine,
  [in, optional]  PVOID                                CompletionRoutineData
);

Parameters

[in] LogFile

A pointer to a LOG_FILE_OBJECT structure that represents the Common Log File System (CLFS) log, or a stream within the log, to which containers are being added or deleted. The value of this parameter is obtained through a call to the ClfsCreateLogFile routine.

[in, optional] ClientCookie

A pointer to a client-supplied cookie. The value of this parameter should be the CLFS_MGMT_CLIENT structure that is obtained through a call to the ClfsMgmtRegisterManagedClient routine.

[in] NewSizeInContainers

The desired size of the log, expressed in the number of containers. There can be at most 1,024 containers for a log file.

[out, optional] ResultingSizeInContainers

The actual size of the log, expressed in the number of containers.

[in, optional] CompletionRoutine

Not used.

[in, optional] CompletionRoutineData

Not used.

Return value

The ClfsMgmtSetLogFileSizeAsClient routine returns an NTSTATUS value.

Return code Description
STATUS_SUCCESS
 The log file size has been set.
STATUS_INVALID_PARAMETER_1
 The value of the LogFile parameter is NULL, or the contents of the NewSizeInContainers parameter is 1.
STATUS_INVALID_PARAMETER_2
 The value of the NewSizeInContainers parameter is NULL.
STATUS_LOG_POLICY_INVALID
 The installed set of policies on the log is invalid. This might be due to an invalid ClfsMgmtPolicyAutoShrink policy or ClfsMgmtPolicyMaximumSize policy.
STATUS_COULD_NOT_RESIZE_LOG
 CLFS management could not delete enough containers to reach the value in NewSizeInContainers.
STATUS_LOG_POLICY_CONFLICT
 A policy on the specified log prevented the operation from completing. This may occur if CLFS management could not add enough containers to the log to reach the value in NewSizeInContainers. This might be due to a conflict with a policy that the client set.
 

This routine might also return other NTSTATUS values.
