    <p>I'm using the Tasking VX toolset (built on Eclipse) and have a fairly basic but fundamental problem that I can't get around... I've RTFMed and am still totally none the wiser.</p> <p>Imagine the simple snippet of code:</p> <pre><code>#include &lt;stdbool.h&gt; bool myFlag = false; </code></pre> <p>If I enable MISRA-C checking, I get the following:</p> <pre><code>MISRA-C rule 10.1 violation: [R] restrict the use of implicit conversions for integer types </code></pre> <p>Eclipse is set up as a C99 implementation, and as per the <a href="http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/stdbool.h.html" rel="nofollow">standard library definition</a>, <code>stdbool.h</code> is defined as:</p> <pre><code>#define bool _Bool #define true 1 #define false 0 </code></pre> <p>I'm assuming that this error is because <code>#define false 0</code> and the tool is implicitly converting to bool?</p> <p>Note: if I cast the assignment, then the error is removed:</p> <pre><code> bool myFlag = (bool)false; </code></pre> <p>But (IMHO) that is masking the problem, not addressing it, and I really do not want to cast every assignment.</p> <p>Tools such as LINT allow you to specify the bool type to stop these sort of false positives... I need the equivalent for Eclipse/Tasking</p> <hr> <p>So my question is this:</p> <p><strong>I suspect that somewhere there is a tool option to tell TASKING that <code>bool</code> is the boolean type, and therefore <code>false</code> and <code>true</code> are OK to be used?</strong></p> <p>Is there?</p> <p>{Please no discussions [on this thread] about the merits (or otherwise) of MISRA}</p>

    1. CODo you get the warning with `bool myFlag = (bool) false;`?

    2. CONo... hence my assumption. But I really do not want to clutter every bool set or test with a cast.

    3. COThe best idea might be to `#define TRUE 1u` etc, but then the code needs to be rewritten to use the upper case version everywhere. The root of the problem is that you are using C99, and MISRA-C:2004 does not allow nor support C99.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
