NAME
CMS_data_create_ex, CMS_data_create
\- Create CMS Data object
SYNOPSIS
Header "SYNOPSIS" .Vb 1
#include <openssl/cms.h>
\&
CMS_ContentInfo *CMS_data_create_ex(BIO *in, unsigned int flags,
OSSL_LIB_CTX *libctx, const char *propq);
CMS_ContentInfo *CMS_data_create(BIO *in, unsigned int flags);
.Ve
DESCRIPTION
Header "DESCRIPTION" \fBCMS_data_create_ex() creates a CMS_ContentInfo structure
with a type NID_pkcs7_data. The data is supplied via the in BIO.
The library context libctx and the property query propq are used when
retrieving algorithms from providers. The flags field supports the
\fBCMS_STREAM flag. Internally CMS_final() is called unless CMS_STREAM is
specified.
The CMS_ContentInfo structure can be freed using CMS_ContentInfo_free\|(3).
\fBCMS_data_create() is similar to CMS_data_create_ex() but uses default values of NULL for the library context libctx and the property query propq.
"RETURN VALUES"
Header "RETURN VALUES" If the allocation fails, CMS_data_create_ex() and CMS_data_create()
return NULL and set an error code that can be obtained by ERR_get_error\|(3).
Otherwise they return a pointer to the newly allocated structure.
"SEE ALSO"
Header "SEE ALSO" \fBERR_get_error\|(3), CMS_final\|(3)
HISTORY
Header "HISTORY" The CMS_data_create_ex() method was added in OpenSSL 3.0.
