<para>
|

|
This function encodes an array of entries pointed to by <emphasis>asn1</emphasis> and terminated
|
||
|
by a NULL entry (i.e. where the <structfield>name</structfield> field of the entry is NULL) into
|
||
|
a newly allocated buffer.
|
||
|
</para>
|
||
|
|
||
|
<para>
|
||
|
The new buffer containing the ASN.1 stream will be stored in <emphasis>newbuf</emphasis>, and the
|
||
|
size of this buffer is stored in <emphasis>size</emphasis>. The application must free this buffer
|
||
|
after use.
