  19 /*  SYNOPSIS */

  21         AROS_LHA(const struct TagItem *, taglist, A2),

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