This is done by treating the size of a <code class="code">void</code> or of a function as 1. </p> <p>A consequence of this is that <code class="code">sizeof</code> is also allowed on <code class="code">void</code> and on function types, and returns 1. </p> <p>The option <samp class="option">-Wpointer-arith</samp> requests a warning if these extensions are used. </p> </div><div class="_attribution"> - <p class="_attribution-p"> - © Free Software Foundation<br>Licensed under the GNU Free Documentation License, Version 1.3.<br> - <a href="https://gcc.gnu.org/onlinedocs/gcc-13.1.0/gcc/Pointer-Arith.html" class="_attribution-link">https://gcc.gnu.org/onlinedocs/gcc-13.1.0/gcc/Pointer-Arith.html</a> - </p> -</div> |
