+int
+DB_ENV-&gt;memp_fcreate(DB_ENV *dbenvp, DB_MPOOLFILE **dbmfp, u_int32_t flags);
+</pre></h3>
+<h1>Description</h1>
+<p>The DB_ENV-&gt;memp_fcreate function creates a DbMpoolFile structure that
+is the handle for a Berkeley DB shared memory buffer pool file. A pointer to
+this structure is returned in the memory to which <b>dbmfp</b> refers.
+Calling the <a href="../api_c/memp_fclose.html">DB_MPOOLFILE-&gt;close</a> function will discard the returned handle.
+<p>The <b>flags</b> parameter is currently unused, and must be set to 0.
+<p>The DB_ENV-&gt;memp_fcreate function returns a non-zero error value on failure and 0 on success.
+<h1>Errors</h1>
+<p>The DB_ENV-&gt;memp_fcreate function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
+If a catastrophic error has occurred, the DB_ENV-&gt;memp_fcreate function may fail and return
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
+in the same way.
