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.
