CMS_final \- finalise a CMS_ContentInfo structure
.SH "SYNOPSIS"

.Vb 1
\& #include <openssl/cms.h>
\&
\& int CMS_final(CMS_ContentInfo *cms, BIO *data, BIO *dcont, unsigned int flags);
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBCMS_final()\fR finalises the structure \fBcms\fR. Its purpose is to perform any
operations necessary on \fBcms\fR (digest computation for example) and set the
appropriate fields. The parameter \fBdata\fR contains the content to be
processed. The \fBdcont\fR parameter contains a \s-1BIO\s0 to write content to after
processing: this is only used with detached data and will usually be set to
\&\s-1NULL.\s0
.SH "NOTES"
.IX Header "NOTES"
This function will normally be called when the \fB\s-1CMS_PARTIAL\s0\fR flag is used. It
should only be used when streaming is not performed because the streaming
I/O functions perform finalisation operations internally.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBCMS_final()\fR returns 1 for success or 0 for failure.
