CMS_DATA_CREATE(3ossl) OpenSSL CMS_DATA_CREATE(3ossl)
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(3) 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(3)
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.
