  20 /*  SYNOPSIS */

  22    AROS_LHA(struct TagItem *, taglist, A2),

  27 /*  FUNCTION
  28     get attributes of a partition table
  29
  30     INPUTS
  31     handle      - Filesystem handle
  32     taglist - list of attributes; unknown tags are ignored
  33         FST_ID      (ULONG *)               - Get 4-characters filesystem ID
  34         FST_NAME    (STRPTR *)              - Get a pointer to filesystem name
  35         FST_FSENTRY (struct FileSysEntry *) - Fill in the given struct FileSysEntry.
  36
  37     RESULT
  38         None.
  39
  40     NOTES
  41         Name is returned as a pointer to internally allocated string. You should copy
  42         it if you want to keep it after filesystem's partition table had been closed.
  43
  44         The following fields in struct FileSysEntry will not be filled in:
  45           - Node name
  46           - fse_Handler
  47           - fse_SegList
  48         You need to query for filesystem's name separately and copy it into BSTR
  49         yourself, if you need to. Loading the handler is done by LoadFileSystem()
  50         function.
