<h4><a name="tag_03_437_03"></a>DESCRIPTION</h4>
|
|
|
|
<blockquote>
|
|
<p>The <i>posix_spawnattr_getsigdefault</i>() function shall obtain the value of the <i>spawn-sigdefault</i> attribute from the
|
|
attributes object referenced by <i>attr</i>.</p>
|
|
|
|
<p>The <i>posix_spawnattr_setsigdefault</i>() function shall set the <i>spawn-sigdefault</i> attribute in an initialized attributes
|
|
object referenced by <i>attr</i>.</p>
|
|
|
|
<p>The <i>spawn-sigdefault</i> attribute represents the set of signals to be forced to default signal handling in the new process
|
|
image (if POSIX_SPAWN_SETSIGDEF is set in the <i>spawn-flags</i> attribute) by a spawn operation. The default value of this
|
|
attribute shall be an empty signal set.</p>
|
|
</blockquote>

|
|
|
<h4><a name="tag_03_437_04"></a>RETURN VALUE</h4>
|
|
|
|
<blockquote>
|
|
<p>Upon successful completion, <i>posix_spawnattr_getsigdefault</i>() shall return zero and store the value of the
|
|
<i>spawn-sigdefault</i> attribute of <i>attr</i> into the object referenced by the <i>sigdefault</i> parameter; otherwise, an error
|
|
number shall be returned to indicate the error.</p>
|
|
|
|
<p>Upon successful completion, <i>posix_spawnattr_setsigdefault</i>() shall return zero; otherwise, an error number shall be
|
|
returned to indicate the error.</p>
