## DB_MPOOLFILE->close()

    #include <db.h>

    int
    DB_MPOOLFILE->close(DB_MPOOLFILE *mpf, u_int32_t flags);

The `DB_MPOOLFILE->close()` method closes the source file indicated by the DB_MPOOLFILE structure. Calling `DB_MPOOLFILE->close()` does not imply a call to DB_MPOOLFILE->sync(); that is, no pages are written to the source file as as a result of calling `DB_MPOOLFILE->close.()`.

If the DB_MPOOLFILE was temporary, any underlying files created for this DB_MPOOLFILE will be removed.

After `DB_MPOOLFILE->close()` has been called, regardless of its return, the DB_MPOOLFILE handle may not be accessed again.

The `DB_MPOOLFILE->close()` method returns a non-zero error value on failure and 0 on success.
