For example, 61<code>@encode(int)</code> is compiled by the compiler into <code>"i"</code>. 62 63 <p><code>@encode</code> does not support type qualifiers other than 64<code>const</code>. For example, <code>@encode(const char*)</code> is valid and 65is compiled into <code>"r*"</code>, while <code>@encode(bycopy char *)</code> is 66invalid and will cause a compilation error. 67 68 </body></html> 69 70
