<p>
On any connection (as a <a class="link" href="GdaConnection.html" title="GdaConnection"><span class="type">GdaConnection</span></a> object), if the database provider used by the connection
supports it, transactions may be started, committed or rolledback, or savepoints added, removed or rolledback.
These operations can be performed using Libgda's API (such as <a class="link" href="GdaConnection.html#gda-connection-begin-transaction" title="gda_connection_begin_transaction ()"><code class="function">gda_connection_begin_transaction()</code></a>), or directly
using some SQL on the connection (usually a "BEGIN;" command). The <a class="link" href="GdaTransactionStatus.html" title="GdaTransactionStatus"><span class="type">GdaTransactionStatus</span></a>'s aim is to
make it easy to keep track of all the commands which have been issued on a connection regarding transactions.
</p>
<p>
One <a class="link" href="GdaTransactionStatus.html" title="GdaTransactionStatus"><span class="type">GdaTransactionStatus</span></a> object is automatically attached to a <a class="link" href="GdaConnection.html" title="GdaConnection"><span class="type">GdaConnection</span></a> when a transaction is started, and
is destroyed when the transaction is finished. A pointer to this object can be fetched using
<a class="link" href="GdaConnection.html#gda-connection-get-transaction-status" title="gda_connection_get_transaction_status ()"><code class="function">gda_connection_get_transaction_status()</code></a> (beware that it should then not be modified). The end user is not
supposed to instantiate <a class="link" href="GdaTransactionStatus.html" title="GdaTransactionStatus"><span class="type">GdaTransactionStatus</span></a> objects
</p>
<p>
<a class="link" href="GdaTransactionStatus.html" title="GdaTransactionStatus"><span class="type">GdaTransactionStatus</span></a>'s attributes are directly accessible using the public members of the object.
