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.

() first appeared in OpenSSL
0.9.8h and has been available since OpenBSD 6.7.
