"DESCRIPTION"
Header "DESCRIPTION" \fBCMS_digest_create_ex() creates a CMS_ContentInfo structure
with a type NID_pkcs7_digest. The data supplied via the in \s-1BIO\s0 is digested
using md. The library context libctx and the property query propq are
used when retrieving algorithms from providers.
The flags field supports the \s-1CMS_DETACHED\s0 and \s-1CMS_STREAM\s0 flags,
Internally CMS_final() is called unless \s-1CMS_STREAM\s0 is specified.
The CMS_ContentInfo structure can be freed using CMS_ContentInfo_free\|(3).
\fBCMS_digest_create() is similar to CMS_digest_create_ex() but uses default values of \s-1NULL\s0 for the library context libctx and the property query propq.
"RETURN VALUES"
Header "RETURN VALUES" If the allocation fails, CMS_digest_create_ex() and CMS_digest_create()
return \s-1NULL\s0 and set an error code that can be obtained by ERR_get_error\|(3).
Otherwise they return a pointer to the newly allocated structure.
