CMS_FINAL(3)               Library Functions Manual               CMS_FINAL(3)

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.

     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.
