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. It's 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.
