(gdbm.info.gz) Reorganization

 
 Database reorganization.
 ************************
 
    The following function should be used very seldom.
 
      ret = gdbm_reorganize(dbf);
 
    The parameter is:
 
 GDBM_FILE dbf
      The pointer returned by `gdbm_open'.
 
    If you have had a lot of deletions and would like to shrink the space
 used by the `gdbm' file, this function will reorganize the database.
 `gdbm' will not shorten the length of a `gdbm' file (deleted file space
 will be reused) except by using this reorganization.
 
    This reorganization requires creating a new file and inserting all
 the elements in the old file `dbf' into the new file. The new file is
 then renamed to the same name as the old file and `dbf' is updated to
 contain all the correct information about the new file. If an error is
 detected, the return value is negative. The value zero is returned
 after a successful reorganization.
