<h3>options</h3>
<p> Specifies how to align struct and class data.</p>
<h5>Syntax</h5>
<p class="code">#pragma options align= alignment</p>
<h5>Parameter</h5>
<p class="code">alignment</p>
<blockquote>
<p>Specifies the boundary on which struct and class data is aligned in memory. Values for alignment range from 1 to 16, or use one of the following preset values:</p>
<table width="75%" border="0" cellpadding="2" cellspacing="0">
<tr>
<th width="25%" scope="col">If alignment is …</th>
<th width="75%" scope="col">The compiler …</th>
</tr>
<tr>
<td class="code">mac68k</td>
<td>Aligns every field on a 2-byte boundaries, unless a field is only 1 byte long. This is the standard alignment for 68K Macintoshes.</td>
</tr>
<tr>
<td class="code">mac68k4byte</td>
<td>Aligns every field on 4-byte boundaries.</td>
</tr>
<tr>
<td class="code">power</td>
<td>Aligns every field on its natural boundary. This is the standard alignment for Power Macintoshes. For example, it aligns a character on a 1-byte boundary and a 16-bit integer on a 2-byte boundary. The compiler applies this alignment recursively to structured data and arrays containing structured data. So, for example, it aligns an array of structured types containing an 4-byte floating point member on an 4-byte boundary.</td>
</tr>
<tr>
<td class="code">native</td>
<td>Aligns every field using the standard alignment. It is equivalent to using mac68k for 68K Macintoshes and power for Power Macintoshes.</td>
</tr>
<tr>
<td class="code">packed</td>
<td>Aligns every field on a 1-byte boundary. It is not available in any panel. This alignment causes your code to crash or run slowly on many platforms. Use it with caution.</td>
</tr>
<tr>
<td class="code">reset</td>
<td>Resets to the value in the previous <span class="code">#pragma options align</span> statement.
<p class="note"><strong>NOTE</strong> There is a space between <span class="code">options</span> and <span class="code">align</span></p>
</td>
</tr>
</table>
</blockquote>
<h5>Targets</h5>
All platforms.<br />
<h5>Remarks</h5>
This pragma corresponds to the Struct Alignment setting in the <Target> Processor or <Target> CodeGen panel.
