158 \&\fICMS_final()\fR finalises the structure \fBcms\fR. It's purpose is to perform any
159 operations necessary on \fBcms\fR (digest computation for example) and set the
160 appropriate fields. The parameter \fBdata\fR contains the content to be
161 processed. The \fBdcont\fR parameter contains a \s-1BIO\s0 to write content to after
162 processing: this is only used with detached data and will usually be set to
163 \&\s-1NULL.\s0
164 .SH "NOTES"
165 .IX Header "NOTES"
166 This function will normally be called when the \fB\s-1CMS_PARTIAL\s0\fR flag is used. It
167 should only be used when streaming is not performed because the streaming
168 I/O functions perform finalisation operations internally.
