int
DB_ENV->memp_fcreate(DB_ENV *dbenvp, DB_MPOOLFILE **dbmfp,
u_int32_t flags);
The DB_ENV->memp_fcreate() method creates a
DB_MPOOLFILE structure that is the handle for a Berkeley DB
cache (that is, a shared memory buffer pool file). A pointer to this structure is returned in the memory to
which dbmfp refers. Calling the
DB_MPOOLFILE->close()
method will discard the returned handle.
The DB_ENV->memp_fcreate()
method returns a non-zero error value on failure and 0 on success.
