## Db::get_pagesize()

    #include <db_cxx.h>

    int
    Db::get_pagesize(u_int32_t *pagesizep);

The `Db::get_pagesize()` method returns the database's current page size, as set by the Db::set_pagesize() method. Note that if `Db::set_pagesize()` was not called by your application, then the default pagesize is selected based on the underlying filesystem I/O block size. If you call `Db::get_pagesize()` before you have opened the database, the value returned by this method is therefore the underlying filesystem I/O block size.

The `Db::get_pagesize()` method may be called only after the database has been opened.

The `Db::get_pagesize()` 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.
