🎀 i2d_CMS_bio_stream 🎀

okay so bestie, this is the i2d_CMS_bio_stream page from the libcrypto Library Functions Manual — yes, that one. Let’s get into it 💅.

✨ 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. That’s the whole main character move.

Other than that, it is literally identical to the function SMIME_write_CMS(3). No cap.

Think of it as a version of i2d_CMS_bio(3) that supports streaming — it’s giving the same energy, just with stream support in the mix ✨.

💖 RETURN VALUES 💖

i2d_CMS_bio_stream() returns 1 for success or 0 for failure. That’s it, bestie — success slay or failure era, no in-between 🫶.

💀 BUGS 💀

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

Not me pointing out the naming situation, but here we are 🙈.
