|  | =head1 NAME | ||
|  | 
 | ||
|  | CMS_data_create_with_libctx, CMS_data_create | ||
|  | - Create CMS Data object | ||
|  | 
 | ||
|  | =head1 SYNOPSIS | ||
|  | 
 | ||
|  |  #include <openssl/cms.h> | ||
|  | 
 | ||
|  |  CMS_ContentInfo *CMS_data_create_with_libctx(BIO *in, unsigned int flags, | ||
|  |                                               OPENSSL_CTX *libctx, | ||
|  |                                               const char *propq); | ||
|  |  CMS_ContentInfo *CMS_data_create(BIO *in, unsigned int flags); | ||
|  | 
 | ||
|  | =head1 DESCRIPTION | ||
|  | 
 | ||
|  | CMS_data_create_with_libctx() creates a B<CMS_ContentInfo> structure | ||
|  | with a type B<NID_pkcs7_data>. The data is supplied via the I<in> BIO. | ||
|  | The library context I<libctx> and the property query I<propq> are used when | ||
|  | retrieving algorithms from providers. The I<flags> field supports the | ||
|  | B<CMS_STREAM> flag. Internally CMS_final() is called unless B<CMS_STREAM> is | ||
|  | specified. | ||
|  | 
 | ||
|  | The B<CMS_ContentInfo> structure can be freed using L<CMS_ContentInfo_free(3)>. | ||
|  | 
 | ||
|  | CMS_data_create() is similar to CMS_data_create_with_libctx() | ||
|  | but uses default values of NULL for the library context I<libctx> and the | ||
|  | property query I<propq>. | ||
|  | 
 | ||
|  | =head1 RETURN VALUES | ||
|  | 
 | ||
|  | If the allocation fails, CMS_data_create_with_libctx() and CMS_data_create() | ||
|  | return NULL and set an error code that can be obtained by L<ERR_get_error(3)>. | ||
|  | Otherwise they return a pointer to the newly allocated structure. | ||
|  |

 | ||
|  | head1 HISTORY | ||
|  | 
 | ||
|  | The CMS_data_create_with_libctx() method was added in OpenSSL 3.0. | ||
