<h1><a name="description">DESCRIPTION</a></h1>
|
|
<p><code>DSA_SIG_new()</code> allocates an empty <strong>DSA_SIG</strong> structure.</p>
|
|
<p><code>DSA_SIG_free()</code> frees the <strong>DSA_SIG</strong> structure and its components. The
|
|
values are erased before the memory is returned to the system.</p>
|
|
<p>DSA_SIG_get0() returns internal pointers to the <strong>r</strong> and <strong>s</strong> values contained
|
|
in <strong>sig</strong>.</p>
|
|
<p>The <strong>r</strong> and <strong>s</strong> values can be set by calling DSA_SIG_set0() and passing the
|
|
new values for <strong>r</strong> and <strong>s</strong> as parameters to the function. Calling this
|
|
function transfers the memory management of the values to the DSA_SIG object,
|
|
and therefore the values that have been passed in should not be freed directly
|
|
after this function has been called.</p>
|
|
<p>
|
|
</p>
|
|
<hr />
|
|
<h1><a name="return_values">RETURN VALUES</a></h1>
|
|
<p>If the allocation fails, <code>DSA_SIG_new()</code> returns <strong>NULL</strong> and sets an
|
|
error code that can be obtained by
|
|
<em>ERR_get_error(3)</em>. Otherwise it returns a pointer
|
|
to the newly allocated structure.</p>
|
|
<p><code>DSA_SIG_free()</code> returns no value.</p>
|
|
<p>DSA_SIG_set0() returns 1 on success or 0 on failure.</p>
