<h4 class="subsection">8.3.2 <code>@encode</code></h4>
|
||
|
|
|
||
|
|
<p>GNU Objective-C supports the <code>@encode</code> syntax that allows you to
|
||
|
|
create a type encoding from a C/Objective-C type. For example,
|
||
|
|
<code>@encode(int)</code> is compiled by the compiler into <code>"i"</code>.
|
||
|
|
</p>
|
||
|
|
<p><code>@encode</code> does not support type qualifiers other than
|
||
|
|
<code>const</code>. For example, <code>@encode(const char*)</code> is valid and
|
||
|
|
is compiled into <code>"r*"</code>, while <code>@encode(bycopy char *)</code> is
|
||
|
|
invalid and will cause a compilation error.
|
||
|
|
