NAME
CMS_final - finalise a CMS_ContentInfo structure
SYNOPSIS
#include <openssl/cms.h>
int CMS_final(CMS_ContentInfo *cms, BIO *data, BIO *dcont, unsigned int flags);
DESCRIPTION
CMS_final() finalises the structure
cms. Its purpose is to perform any
operations necessary on
cms (digest computation for example) and set the
appropriate fields. The parameter
data contains the content to be
processed. The
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.
NOTES
This function will normally be called when the
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.
RETURN VALUES
CMS_final() returns 1 for success or 0 for failure.
