// [Member functions]
//
// IUniformResourceLocator::SetURL
//
//   This member function sets an object's URL.
//
//   The dwInFlags parameter specifies the behavior:
//
//  IURL_SETURL_FL_GUESS_PROTOCOL: The protocol scheme is guessed and added
//   to the URL, if it is not specified in pcszURL.
//
//  IURL_SETURL_FL_USE_DEFAULT_PROTOCOL: The default protocol scheme is added
//   to the URL, if it is not specified in pcszURL.
//
//   The function returns S_OK if the object's URL is set successfully.
//  Otherwise, an error code is returned:
//
//  E_OUTOFMEMORY:  There is not enough memory to complete the operation.
//
//  IS_E_EXEC_FAILED:  The URL's protocol handler failed to run.
//
//  URL_E_INVALID_SYNTAX:  The URL's syntax is invalid.
//
//  URL_E_UNREGISTERED_PROTOCOL:  The URL's protocol does not have a
//   registered protocol handler.
//
//
// IUniformResourceLocator::GetURL
//
//   This member function retrieves an object's URL.  The ppszURL is a
//  pointer to a PSTR to be filled in which a pointer to the object's
//  URL.  When finished, this string should be freed using IMalloc::Free().
//
//   The function returns S_OK if the object's URL was retrieved
//  successfully.  If the object does not have a URL associated with it,
//  then S_FALSE is returned and *ppszURL is set to NULL.  Otherwise, an
//  error code is returned:
//
//  E_OUTOFMEMORY:  There is not enough memory to complete the operation.
//
//  IS_E_EXEC_FAILED:  The URL's protocol handler failed to run.
//
//  URL_E_INVALID_SYNTAX:  The URL's syntax is invalid.
//
//  URL_E_UNREGISTERED_PROTOCOL:  The URL's protocol does not have a
//   registered protocol handler.
//
//
// IUniformResourceLocator::InvokeCommand
//
//   This member function invokes a command on an object's URL.  The purlici
//  parameter is a pointer to a URLINVOKECOMMANDINFO structure which
//  describes the command to be invoked.
//
//   The function returns S_OK if the object's URL was opened successfully.
//  If the object does not have a URL associated with it, the function
//  returns S_FALSE.  Otherwise, an error code is returned:
//
//  E_OUTOFMEMORY:  There is not enough memory to complete the operation.
//
//  IS_E_EXEC_FAILED:  The URL's protocol handler failed to run.
//
//  URL_E_INVALID_SYNTAX:  The URL's syntax is invalid.
