<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>General structure for client/serve message data exchange. </p>
<p>It is used in the calls of <code>SHMMessageSend</code> and <code>SHMMessageReceive</code>. The field <code>data</code> is interpreted according to the values of the fields <code>mtype</code> and <code>command</code>. The possible structs the <code>data</code> field can represent are: <code><a class="el" href="structversion__struct.html" title="Information transmitted in CMD_VERSION Messages.">version_struct</a></code> <code><a class="el" href="structclient__struct.html">client_struct</a></code> <code><a class="el" href="structestablish__struct.html" title="Information contained in SCARD_ESTABLISH_CONTEXT Messages.">establish_struct</a></code> <code><a class="el" href="structrelease__struct.html" title="Information contained in SCARD_RELEASE_CONTEXT Messages.">release_struct</a></code> <code><a class="el" href="structconnect__struct.html" title="contained in SCARD_CONNECT Messages.">connect_struct</a></code> <code><a class="el" href="structreconnect__struct.html" title="contained in SCARD_RECONNECT Messages.">reconnect_struct</a></code> <code><a class="el" href="structdisconnect__struct.html" title="contained in SCARD_DISCONNECT Messages.">disconnect_struct</a></code> <code><a class="el" href="structbegin__struct.html" title="contained in SCARD_BEGIN_TRANSACTION Messages.">begin_struct</a></code> <code><a class="el" href="structend__struct.html" title="contained in SCARD_END_TRANSACTION Messages.">end_struct</a></code> <code><a class="el" href="structcancel__struct.html" title="contained in SCARD_CANCEL Messages.">cancel_struct</a></code> <code><a class="el" href="structstatus__struct.html" title="contained in SCARD_STATUS Messages.">status_struct</a></code> <code><a class="el" href="structtransmit__struct.html" title="contained in SCARD_TRANSMIT Messages.">transmit_struct</a></code> <code><a class="el" href="structcontrol__struct.html" title="contained in SCARD_CONTROL Messages.">control_struct</a></code> <code><a class="el" href="structgetset__struct.html" title="contained in SCARD_GET_ATTRIB and Messages.">getset_struct</a></code> </p>
