LIBRESSL-PEM_WRITE_BIO_PKCS7_STREAM(3)

💖 PEM_WRITE_BIO_PKCS7_STRE(3) — Library Functions Manual, but make it cute 💖

okay so bestie, this page is literally the PEM_write_bio_PKCS7_stream(3) moment — from the Library Functions Manual (yes, the header is right there being all PEM_WRITE_BIO_PKCS7_STRE(3), don't worry about the truncation vibe 😭). It's giving PKCS7 structure, but PEM format and streaming. Let's go 🫶

🌸 NAME 🌸

PEM_write_bio_PKCS7_stream — output PKCS7 structure in PEM format.

---

✨ SYNOPSIS ✨

library “libcrypto” #include <openssl/pkcs7.h>

int
PEM_write_bio_PKCS7_stream(BIO *out, PKCS7 *p7, BIO *data, int flags);

🎀 DESCRIPTION 🎀

okay so PEM_write_bio_PKCS7_stream() outputs a PKCS7 structure in PEM format. That's the whole main character move 💅.

It is otherwise identical to the function SMIME_write_PKCS7(3). Periodt.

This function is effectively a version of PEM_write_bio_PKCS7(3) supporting streaming. No cap — streaming support is the whole little upgrade here ✨.

💜 RETURN VALUES 💜

• Upon successful completion, 1 is returned ✨
• otherwise 0 is returned and an error code can be retrieved with ERR_get_error(3) 😭
