CMS_final(3)                        OpenSSL                       CMS_final(3)



NAME
       CMS_final - finalise a CMS_ContentInfo structure

LIBRARY
       libcrypto, -lcrypto

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.
