NAME

       CMS_data_create_ex, CMS_data_create - Create CMS Data object

SYNOPSIS

        #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);

DESCRIPTION

       CMS_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
       CMS_STREAM flag. Internally CMS_final() is called unless CMS_STREAM is specified.

       The CMS_ContentInfo structure can be freed using CMS_ContentInfo_free(3).

       CMS_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

       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.

       The CMS_data_create_ex() method was added in OpenSSL 3.0.
