List of main functions

Main fst-functions

   fstopt(optName, optValue, setOget=0) 
       Set or print FST option. Use to suppress excessive "talking" of the following fst-functions.

   fstopenall(paths, filemode='RND+R/O', verbose=None) 
        Open all fstfiles found in path

   fstcloseall(iunit, verbose=None) 
        Close all files associated with provided file unit number.

   fstlir(iunit, datev=-1, etiket=' ', ip1=-1, ip2=-1, ip3=-1, typvar=' ', nomvar=' ', dtype=None, rank=None, dataArray=None) 
        Reads the next record that matches the research keys

   fstlirx(key, iunit, datev=-1, etiket=' ', ip1=-1, ip2=-1, ip3=-1, typvar=' ', nomvar=' ', dtype=None, rank=None, dataArray=None) 
        Reads the next record after 'key' that matches the research keys

   fstlis(iunit, dtype=None, rank=None, dataArray=None) 
        Reads the next record that matches the research criterias

   fstinf(iunit, datev=-1, etiket=' ', ip1=-1, ip2=-1, ip3=-1, typvar=' ', nomvar=' ')
        Locates the next record that matches the research keys

   fstinfx(key, iunit, datev=-1, etiket=' ', ip1=-1, ip2=-1, ip3=-1, typvar=' ', nomvar=' ') 
        Locates the next record after 'key' that matches the research keys

   fstinl(iunit, datev=-1, etiket=' ', ip1=-1, ip2=-1, ip3=-1, typvar=' ', nomvar=' ', nrecmax=-1)
        Locate all the records matching the research keys

   fstluk(key, dtype=None, rank=None, dataArray=None) 
        Read the record at position given by key/handle found by 'fstinf', 'fstinfx', or 'fstinl'

   fstprm(key) 
        Get all the description parameters of the record needed for 'fstecr'

   fstecr(iunit, data, meta=None, rewrite=True) 
        Writes record to file previously opened with fnom+fstouv

Other fst-functions

   fst_edit_dir(key, datev=-1, dateo=-1, deet=-1, npas=-1, ni=-1, nj=-1, nk=-1, ip1=-1, ip2=-1, ip3=-1, typvar=' ', nomvar=' ', etiket=' ', grtyp=' ', ig1=-1, ig2=-1, ig3=-1, ig4=-1, datyp=-1, keep_dateo=False)
   fst_version()
   fsteff(key)
   fstfrm(iunit)
   fstlnk(unitList)
   fstnbr(iunit)
   fstnbrv(iunit)
   fstouv(iunit, filemode='RND+R/W')
   fstsui(iunit)
   fstvoi(iunit, options=' ')
