DbMpoolFile::put

APIRef

#include <db_cxx.h>

int DbMpoolFile::put(void *pgaddr, u_int32_t flags);

Description

The DbMpoolFile::put method indicates that the page to which pgaddr refers can be evicted from the pool. The pgaddr argument must be an address previously returned by DbMpoolFile::get.

The flags value must be set to 0 or by bitwise inclusively OR'ing together one or more of the following values:

DB_MPOOL_CLEAN
Clear any previously set modification information (that is, don't bother writing the page back to the source file).

DB_MPOOL_DIRTY
The page has been modified and must be written to the source file before being evicted from the pool.

DB_MPOOL_DISCARD
The page is unlikely to be useful in the near future, and should be discarded before other pages in the pool.

The DB_MPOOL_CLEAN and DB_MPOOL_DIRTY flags are mutually exclusive.

The DbMpoolFile::put method either returns a non-zero error value or throws an exception that encapsulates a non-zero error value on failure, and returns 0 on success.

Errors

The DbMpoolFile::put method may fail and throw an exception or return a non-zero error for the following conditions:

EACCES
The DB_MPOOL_DIRTY flag was set and the source file was not opened for writing.

EINVAL
An invalid flag value or parameter was specified.

The pgaddr argument does not refer to a page returned by DbMpoolFile::get.

More than one of the DB_MPOOL_CLEAN and DB_MPOOL_DIRTY flags was set.

The DbMpoolFile::put method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods. If a catastrophic error has occurred, the DbMpoolFile::put method may fail and either return DB_RUNRECOVERY or throw an exception encapsulating DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
