###

    #include <db.h>

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

# Description

The DB_MPOOLFILE->close function 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.

The flags parameter is currently unused, and must be set to 0.

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

The DB_MPOOLFILE->close function returns a non-zero error value on failure and 0 on success.

# Errors

The DB_MPOOLFILE->close function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions. If a catastrophic error has occurred, the DB_MPOOLFILE->close function may fail and return DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
