-  <title>Idiom Support</title>
-<para>
-The DBE specification introduces the notion of idioms, which are
-groups of X requests which can be executed more efficiently when taken
-as a whole compared to being performed individually and sequentially.
-This following server internal support to allows DBE
-implementations, as well as other parts of the server,
-to do idiom processing.
-</para>
-<para>
-<blockquote><programlisting>
-
-	xReqPtr PeekNextRequest(xReqPtr req, ClientPtr client, Bool readmore)
-</programlisting></blockquote>
-If req is NULL, the return value will be a pointer to the start of the
-complete request that follows the one currently being executed for the
-client.  If req is not NULL, the function assumes that req is a
-pointer to a request in the client's request buffer, and the return
-value will be a pointer to the the start of the complete request that
-follows req.  If the complete request is not available, the function
-returns NULL; pointers to partial requests will never be returned.  If
-(and only if) readmore is TRUE, PeekNextRequest should try to read an
-additional request from the client if one is not already available in
-the client's request buffer.  If PeekNextRequest reads more data into
-the request buffer, it should not move or change the existing data.
-</para>
-<para>
-<blockquote><programlisting>
-
-	void SkipRequests(xReqPtr req, ClientPtr client, int numskipped)
-</programlisting></blockquote>
-The requests for the client up to and including the one specified by
-req will be skipped.  numskipped must be the number of requests being
-skipped.  Normal request processing will resume with the request that
-follows req.  The caller must not have modified the contents of the
-request buffer in any way (e.g., by doing byte swapping in place).
-</para>
-<para>
-Additionally, two macros in os.h operate on the xReq
-pointer returned by PeekNextRequest:
-<blockquote><programlisting>
-
-	int ReqLen(xReqPtr req, ClientPtr client)
-</programlisting></blockquote>
-The value of ReqLen is the request length in bytes of the given xReq.
-<blockquote><programlisting>
-
-	otherReqTypePtr CastxReq(xReq *req, otherReqTypePtr)
-</programlisting></blockquote>
-The value of CastxReq is the conversion of the given request pointer
-to an otherReqTypePtr (which should be a pointer to a protocol
-structure type).  Only those fields which come after the length field
-of otherReqType may be accessed via the returned pointer.
-</para>
-<para>
-Thus the first two fields of a request, reqType and data, can be
-accessed directly using the xReq * returned by PeekNextRequest.  The
-next field, the length, can be accessed with ReqLen.  Fields beyond
-that can be accessed with CastxReq.  This complexity was necessary
-because of the reencoding of core protocol that can happen due to the
-BigRequests extension.
