CMS_data_create(3)                  OpenSSL                 CMS_data_create(3)



NAME
       CMS_data_create_ex, CMS_data_create - Create CMS Data object

LIBRARY
       libcrypto, -lcrypto

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.
