The <code class="methodname">DbEnv::memp_fcreate()</code> method creates a

<a class="link" href="memp.html" title="Chapter 9. The DbMpoolFile Handle">DbMpoolFile</a> 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 <span class="bold"><strong>dbmfp</strong></span> refers. Calling the

<a class="xref" href="mempfclose.html" title="DbMpoolFile::close()">DbMpoolFile::close()</a> method will discard the returned handle.
