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.
