|
|

=head1 DESCRIPTION
|
|
|
|
|
|
|
|
|
|
CMS_final() finalises the structure B<cms>. It's purpose is to perform any
|
|
|
|
|
operations necessary on B<cms> (digest computation for example) and set the
|
|
|
|
|
appropriate fields. The parameter B<data> contains the content to be
|
|
|
|
|
processed. The B<dcont> parameter contains a BIO to write content to after
|
|
|
|
|
processing: this is only used with detached data and will usually be set to
|
|
|
|
|
NULL.

=head1 NOTES
|
|
|
|
|
|
|
|
|
|
This function will normally be called when the B<CMS_PARTIAL> flag is used. It
|
|
|
|
|
should only be used when streaming is not performed because the streaming
|
|
|
|
|
I/O functions perform finalisation operations internally.
