INetDiagHelper::GetCacheTime method (ndhelper.h)

  • Article

The GetCacheTime method specifies the time when cached results of a diagnosis and repair operation have expired.

Syntax

HRESULT GetCacheTime(
  [out] FILETIME *pCacheTime
);

Parameters

[out] pCacheTime

A pointer to a FILETIME structure.

Return value

Return code Description
S_OK
 The operation succeeded.
E_OUTOFMEMORY
 There is not enough memory available to complete this operation.
E_INVALIDARG
 One or more parameters has not been provided correctly.
E_NOTIMPL
 This optional method is not implemented.
E_ACCESSDENIED
 The caller does not have sufficient privileges to perform the diagnosis or repair operation.
E_ABORT
 The diagnosis or repair operation has been canceled.
 

Helper Class Extensions may return HRESULTS that are specific to the failures encountered in the function.

Remarks

This method is not required when building a Helper Class Extension.

The default behavior is to return the current time so that the results will not be cached. Setting a cache time can increase diagnosis efficiency since NDF will not call on the extension to re-diagnose an issue unless the cache time has expired.

The FILETIME structure is a 64-bit value representing the number of 100-nanosecond intervals since January 1, 1601 (UTC).
