|
|
\&\fICMS_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.

|

\&\fICMS_final()\fR returns 1 for success or 0 for failure.
