<div class="paragraph"><p>The <span class="monospaced">__noreturn</span> modifier can be placed immediately after a function type declaration to specify that
a function can never return. For example, the <span class="monospaced">exit</span> function is marked with <span class="monospaced">__noreturn</span>.</p></div>
<div class="paragraph"><p>It is not necessary for functions that call <span class="monospaced">__noreturn</span> functions such as <span class="monospaced">exit</span> to explicitly specify
that they cannot return. The compiler will automatically determine that such functions are <span class="monospaced">__noreturn</span>.
This attribute is usually only necessary with functions that issue system calls that cause the
process to exit, or to transition to a new codebase (such as <span class="monospaced">execve</span>).</p></div>
