The SMS Utility (SMSU) is a DLL. The SMSU provides utility functionality for SMS messages. </shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody><section><title>Buffer and streams</title> <p>The SMSU creates the buffers, read streams and write streams required for the SMS stack. The SMSU creates a temporary buffer of 256 bytes to store the Protocol Data Units (PDU)s in the SMS stack. The PDUs are processed by the SMS stack in the temporary buffers. </p> </section> <section><title>SMS event logger</title> <p>SMSU provides the required functionality to log the events using the <xref href="GUID-5B63D14D-007D-566F-A065-1A25FE4B97A3.dita">Log engine</xref>. The SMS stack logs all the sent and received messages using the Log engine. The Log engine is used by the User Interface (UI) implementers to display the log to the users. Client can use this functionality, only if the Log engine is installed in a device. </p> </section> <section><title>SMS address</title> <p>The <xref href="GUID-F278803A-546A-3E04-B208-5A963008C238.dita"><apiname>TSmsAddr</apiname></xref> of the SMSU provides methods to store the SMS address values. The SMS addresses are stored in a <xref href="GUID-C8CFCCDE-E04A-3084-86BF-7A2AF729EEEB.dita"><apiname>TSmsAddrFamily</apiname></xref> type. The <xref href="GUID-F278803A-546A-3E04-B208-5A963008C238.dita"><apiname>TSmsAddr</apiname></xref> also enables the SMS stack to bind the packets to the socket server using the parameters defined in <xref href="GUID-F278803A-546A-3E04-B208-5A963008C238.dita"><apiname>TSmsAddr</apiname></xref>. <xref href="GUID-F278803A-546A-3E04-B208-5A963008C238.dita#GUID-F278803A-546A-3E04-B208-5A963008C238/GUID-3976BF09-8CE1-3DB7-BDDE-04C5B5137402"><apiname>TSmsAddr::SetSmsAddrFamily()</apiname></xref> can be used to define the socket and port to bind the packets.
