<h4 class="subsection">3.18.52 VMS Options</h4>
|
|
|
|
<p>These ‘<samp>-m</samp>’ options are defined for the VMS implementations:
|
|
</p>
|
|
<dl compact="compact">
|
|
<dt><code>-mvms-return-codes</code></dt>
|
|
<dd><a name="index-mvms_002dreturn_002dcodes"></a>
|
|
<p>Return VMS condition codes from <code>main</code>. The default is to return POSIX-style
|
|
condition (e.g. error) codes.
|
|
</p>
|
|
</dd>
|
|
<dt><code>-mdebug-main=<var>prefix</var></code></dt>
|
|
<dd><a name="index-mdebug_002dmain_003dprefix"></a>
|
|
<p>Flag the first routine whose name starts with <var>prefix</var> as the main
|
|
routine for the debugger.
|
|
</p>
|
|
</dd>
|
|
<dt><code>-mmalloc64</code></dt>
|
|
<dd><a name="index-mmalloc64"></a>
|
|
<p>Default to 64-bit memory allocation routines.
|
|
</p>
|
|
</dd>
|
|
<dt><code>-mpointer-size=<var>size</var></code></dt>
|
|
<dd><a name="index-mpointer_002dsize_003dsize"></a>
|
|
<p>Set the default size of pointers. Possible options for <var>size</var> are
|
|
‘<samp>32</samp>’ or ‘<samp>short</samp>’ for 32 bit pointers, ‘<samp>64</samp>’ or ‘<samp>long</samp>’
|
|
for 64 bit pointers, and ‘<samp>no</samp>’ for supporting only 32 bit pointers.
|
|
The later option disables <code>pragma pointer_size</code>.
