## DbMpoolFile::set_maxsize()

    #include <db_cxx.h>

    int
    DbMpoolFile::set_maxsize(u_int32_t gbytes, u_int32_t bytes);

Set the maximum size for the file to be gbytes gigabytes plus bytes. Attempts to allocate new pages in the file after the limit has been reached will fail.

To set the maximum file size for a particular database, call the `DbMpoolFile::set_maxsize()` method using the DbMpoolFile handle stored in the mpf field of the Db handle. Attempts to insert new items into the database after the limit has been reached may fail.

The `DbMpoolFile::set_maxsize()` method configures a file in the cache, not only operations performed using the specified DbMpoolFile handle.

The `DbMpoolFile::set_maxsize()` method may be called at any time during the life of the application.

The `DbMpoolFile::set_maxsize()` 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.
