1=pod 2 3=head1 NAME 4 5CMS_final - finalise a CMS_ContentInfo structure 6 7=head1 SYNOPSIS 8 9 #include <openssl/cms.h> 10 11 int CMS_final(CMS_ContentInfo *cms, BIO *data, BIO *dcont, unsigned int flags); 12 13=head1 DESCRIPTION 14 15CMS_final() finalises the structure B<cms>. Its purpose is to perform any 16operations necessary on B<cms> (digest computation for example) and set the 17appropriate fields. The parameter B<data> contains the content to be 18processed. The B<dcont> parameter contains a BIO to write content to after 19processing: this is only used with detached data and will usually be set to 20NULL. 21 22=head1 NOTES 23 24This function will normally be called when the B<CMS_PARTIAL> flag is used. It 25should only be used when streaming is not performed because the streaming 26I/O functions perform finalisation operations internally. 27 28=head1 RETURN VALUES 29 30CMS_final() returns 1 for success or 0 for failure. 31 32=head1 SEE ALSO 33 34L<ERR_get_error(3)>, L<CMS_sign(3)>, 35L<CMS_encrypt(3)> 36 37=head1 COPYRIGHT 38 39Copyright 2008-2019 The OpenSSL Project Authors.
