IAccessControl::IsAccessAllowed (Windows Embedded CE 6.0)

  • 아티클

1/6/2010

This method determines whether the given trustee has access rights to the object or property.

Syntax

HRESULT IsAccessAllowed(
  PTRUSTEEW pTrustee, 
  LPWSTR lpProperty, 
  ACCESS_RIGHTS AccessRights, 
  BOOL* pfAccessAllowed 
);

Parameters

  • pTrustee
    [in] Pointer to the trustee.
  • lpProperty
    [in] Name of the property. If you are using the COM implementation of the IAccessControl interface, this parameter must be NULL.
  • AccessRights
    [in] Access rights on the object. ACCESS_RIGHTS is defined as a ULONG. If you are using the COM implementation of IAccessControl, this value must be either zero or 1 (COM_RIGHTS_EXECUTE).
  • pfAccessAllowed
    [out] Pointer to a BOOL variable that is set to TRUE if access is allowed; otherwise, it is set to FALSE.

Return Value

None.

Remarks

In the system-supplied implementation of IAccessControl (CLSID_DCOMAccessControl), IsAccessAllowed can be called only during a distributed COM call, and the only valid trustee name is the name of the client.
