<h4><a name="tag_03_431_03"></a>DESCRIPTION</h4>
|
|
|
|
<blockquote>
|
|
<p>The <i>posix_spawn_file_actions_destroy</i>() function shall destroy the object referenced by <i>file_actions</i>; the object
|
|
becomes, in effect, uninitialized. An implementation may cause <i>posix_spawn_file_actions_destroy</i>() to set the object
|
|
referenced by <i>file_actions</i> to an invalid value. A destroyed spawn file actions object can be reinitialized using
|
|
<i>posix_spawn_file_actions_init</i>(); the results of otherwise referencing the object after it has been destroyed are
|
|
undefined.</p>
|
|
|
|
<p>The <i>posix_spawn_file_actions_init</i>() function shall initialize the object referenced by <i>file_actions</i> to contain no
|
|
file actions for <a href="../functions/posix_spawn.html"><i>posix_spawn</i>()</a> or <a href=
|
|
"../functions/posix_spawnp.html"><i>posix_spawnp</i>()</a> to perform.</p>
|
|
|
|
<p>A spawn file actions object is as defined in <a href=
|
|
"posix_spawn_file_actions_addclose.html"><i>posix_spawn_file_actions_addclose</i>()</a> .</p>
|
|
|
|
<p>The effect of initializing an already initialized spawn file actions object is undefined.</p>
|
|
</blockquote>
|
|
|
|
<h4><a name="tag_03_431_04"></a>RETURN VALUE</h4>
|
|
|
|
<blockquote>
|
|
<p>Upon successful completion, these functions shall return zero; otherwise, an error number shall be returned to indicate the
|
|
error.</p>
|

</blockquote>

|
|
<h4><a name="tag_03_431_05"></a>ERRORS</h4>
|
|
|
|
<blockquote>
|
|
<p>The <i>posix_spawn_file_actions_init</i>() function shall fail if:</p>
|
|
|
|
<dl compact>
|
|
<dt>[ENOMEM]</dt>
|
|
|
|
<dd>Insufficient memory exists to initialize the spawn file actions object.</dd>
|
|
</dl>
|
|
|
|
<p>The <i>posix_spawn_file_actions_destroy</i>() function may fail if:</p>
|
|
|
|
<dl compact>
|
|
<dt>[EINVAL]</dt>
|
|
|
|
<dd>The value specified by <i>file_actions</i> is invalid.</dd>
