(gdbm.info.gz) Delete

 
 Removing records from the database.
 ***********************************
 
    To remove some data from the database:
 
      ret = gdbm_delete(dbf, key);
 
    The parameters are:
 
 GDBM_FILE dbf
      The pointer returned by `gdbm_open'.
 
 datum key
      The `key' data.
 
    The ret value is -1 if the item is not present or the requester is a
 reader.  The ret value is 0 if there was a successful delete.
 
    `gdbm_delete' removes the keyed item and the `key' from the database
 `dbf'. The file on disk is updated to reflect the structure of the new
 database before returning from this function.
