  25.  
  26.      _GGGG_EEEE_TTTT_FFFF_SSSS_IIII_NNNN_DDDD      Translate _f_s_n_a_m_e, a null-terminated file-system type

  28.  
  29.      _GGGG_EEEE_TTTT_FFFF_SSSS_TTTT_YYYY_PPPP      Translate _f_s__i_n_d_e_x, a file-system type index, into a null-

  31.                    the buffer pointed to by _b_u_f; this buffer must be at least
  32.                    of size _FFFF_SSSS_TTTT_YYYY_PPPP_SSSS_ZZZZ as defined in _<<<<_ssss_yyyy_ssss_////_ffff_ssss_tttt_yyyy_pppp_...._hhhh_>>>>.

  48.      Upon successful completion, _ssss_yyyy_ssss_ffff_ssss returns the file-system type index if
  49.      the _o_p_c_o_d_e is _GGGG_EEEE_TTTT_FFFF_SSSS_IIII_NNNN_DDDD, a value of 0 if the _o_p_c_o_d_e is _GGGG_EEEE_TTTT_FFFF_SSSS_TTTT_YYYY_PPPP, or the
  50.      number of file system types configured if the _o_p_c_o_d_e is _GGGG_EEEE_TTTT_NNNN_FFFF_SSSS_TTTT_YYYY_PPPP.
