Description: DbMpoolFile::set_ftype

The DbMpoolFile::set_ftype method specifies a file type for the purposes of input or output processing of the file's pages as they are read from or written to, the backing filesystem store.

The DbMpoolFile::set_ftype method configures a file in the memory pool, not only operations performed using the specified DbMpoolFile handle.

The DbMpoolFile::set_ftype method may not be called after the DbMpoolFile::open method is called. If the file is already open in the memory pool when DbMpoolFile::open is called, the information specified to DbMpoolFile::set_ftype will replace the existing information.

The DbMpoolFile::set_ftype 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.

Parameters

ftype

The ftype parameter sets the file's type for the purposes of input and output processing. The ftype must be the same as a ftype parameter previously specified to the DbEnv::memp_register method. (See the DbEnv::memp_register documentation for more information.)

Description: DbMpoolFile::get_ftype

The DbMpoolFile::get_ftype method returns the .

The DbMpoolFile::get_ftype method may be called at any time during the life of the application.
