15 File Locking.
With locking disabled (if
gdbm_open was called with ‘GDBM_NOLOCK’),
the user may want to perform their own file locking on the database file
in order to prevent multiple writers operating on the same file
In order to support this, the
gdbm_fdesc routine is provided.
- gdbm interface: int gdbm_fdesc (GDBM_FILE dbf)
Returns the file descriptor of the database dbf. This value can be used as an argument to
lockfor similar calls.
