<h1><a name="description">DESCRIPTION</a></h1>
|
|
<p><code>CMS_uncompress()</code> extracts and uncompresses the content from a CMS
|
|
CompressedData structure <strong>cms</strong>. <strong>data</strong> is a BIO to write the content to and
|
|
<strong>flags</strong> is an optional set of flags.</p>
|
|
<p>The <strong>dcont</strong> parameter is used in the rare case where the compressed content
|
|
is detached. It will normally be set to NULL.</p>
|
|
<p>
|
|
</p>
|
|
<hr />
|
|
<h1><a name="notes">NOTES</a></h1>
|
|
<p>The only currently supported compression algorithm is zlib: if the structure
|
|
indicates the use of any other algorithm an error is returned.</p>
|
|
<p>If zlib support is not compiled into OpenSSL then <code>CMS_uncompress()</code> will always
|
|
return an error.</p>
|
|
<p>The following flags can be passed in the <strong>flags</strong> parameter.</p>
|
|
<p>If the <strong>CMS_TEXT</strong> flag is set MIME headers for type <strong>text/plain</strong> are deleted
|
|
from the content. If the content is not of type <strong>text/plain</strong> then an error is
|
|
returned.</p>
|
|

|
|
<h1><a name="return_values">RETURN VALUES</a></h1>
|
|
<p><code>CMS_uncompress()</code> returns either 1 for success or 0 for failure. The error can
|
|
be obtained from <code>ERR_get_error(3)</code></p>
|
|
<p>
|
|
</p>
|
|
<hr />
|
|
<h1><a name="bugs">BUGS</a></h1>
|
|
<p>The lack of single pass processing and the need to hold all data in memory as
|
|
mentioned in <code>CMS_verify()</code> also applies to <code>CMS_decompress()</code>.</p>
