[Java]
    String getFileTagAsAnsiString( String fileName, String tagName, int tagID)

Parameters

  • [Plain C] Storage - handle to the storage returned by Create or Open function.
  • [Plain C] ValueBuffer - buffer containing tag value.
  • [Plain C] ValueBufferSize - size of the buffer containing tag value.
  • [C++ (DLL/Lib)] Value - tag value.
  • FileName - the full file name in the SolFSStorage.
  • TagName - name of the tag or empty value, if TagID is to be used.
  • TagID - tag unique ID, must be in range of [0x8000..0xCFFF] or 0 if TagName is to be used.

Return value

    Tag value.

     [Plain C]  0 if the function succeeded or one of Error codes if the function failed.

Description

Use this method to get values of ANSI string tag. You need to specify either TagName (in this case TagID parameter is ignored) or TagID (in this case TagName parameter is ignored).
Note, that in SolFS queries all ANSI strings are converted to UNICODE. It is recommended to use only ASCII characters in ANSI strings.
