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. 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.
