#include <openssl/cms.h>

int
i2d_CMS_bio_stream(BIO *out, CMS_ContentInfo *cms, BIO *data, int flags);

() outputs a CMS_ContentInfo structure in BER format.

It is otherwise identical to the function SMIME_write_CMS(3).

This function is effectively a version of i2d_CMS_bio(3) supporting streaming.

i2d_CMS_bio_stream() returns 1 for success or 0 for failure.

i2d_CMS_bio_stream() first appeared in OpenSSL 1.0.0 and has been available since OpenBSD 6.7.

The prefix "i2d" is arguably wrong because the function outputs BER format.
