CMS_data_create_ex, CMS_data_create
|
|
- Create CMS Data object

|
|
|
=head1 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);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
CMS_data_create_ex() 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_ex()
|
|
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_ex() 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.
|
|
