# NAME

`i2d_CMS_bio_stream` — output CMS_ContentInfo structure in BER format

# SYNOPSIS

library “libcrypto”
`#include <openssl/cms.h>`

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

# DESCRIPTION

`i2d_CMS_bio_stream`() 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.

# RETURN VALUES

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

# SEE ALSO

CMS_ContentInfo_new(3), CMS_encrypt(3), CMS_sign(3), ERR_get_error(3), PEM_write_bio_CMS_stream(3), SMIME_write_CMS(3)

# HISTORY

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

# BUGS

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