9 #include <openssl/cms.h>
10
11 int CMS_final(CMS_ContentInfo *cms, BIO *data, BIO *dcont, unsigned int flags);
12
13=head1 DESCRIPTION
14
15CMS_final() finalises the structure B<cms>. Its purpose is to perform any
16operations necessary on B<cms> (digest computation for example) and set the
17appropriate fields. The parameter B<data> contains the content to be
18processed. The B<dcont> parameter contains a BIO to write content to after
19processing: this is only used with detached data and will usually be set to
20NULL.
21
22=head1 NOTES
23
24This function will normally be called when the B<CMS_PARTIAL> flag is used. It
25should only be used when streaming is not performed because the streaming
26I/O functions perform finalisation operations internally.
