OSSL_STORE_ATTACH(3SSL)
π OSSL_STORE_ATTACH β bestie, let's read objects straight off a BIO
okay so this is the OpenSSL manpage OSSL_STORE_ATTACH(3SSL) and honestly? it's a tiny page but it's lowkey iconic. basically it's the "i already have a BIO, don't make me find a URI" girl. let's get into it π
β¨ NAME β¨
OSSL_STORE_attach β functions to read objects from a BIO. yes that's literally the whole job description, she's focused π
πΈ SYNOPSIS πΈ
#include <openssl/store.h>
OSSL_STORE_CTX *OSSL_STORE_attach(BIO *bio, const char *scheme,
OSSL_LIB_CTX *libctx, const char *propq,
const UI_METHOD *ui_method, void *ui_data,
const OSSL_PARAM params[],
OSSL_STORE_post_process_info_fn post_process,
void *post_process_data);
look at all those parameters. she's got range, fr fr π¦
π¦ DESCRIPTION π¦
So the tea is: OSSL_STORE_attach() works exactly like OSSL_STORE_open(3), with one glow-up difference β instead of handing her a <italic>uri</italic>, you hand her a <italic>bio</italic> directly. that's the whole plot twist, bestie π«Ά
And you also pass in a <italic>scheme</italic>, which is what tells her which loader should be doing the processing of your data. like picking which friend handles the aux cord β somebody's gotta decide the vibe π
π‘ IMPORTANT LITTLE DETAIL (no cap): if the call is successful, the reference count of the BIO object gets increased by 1. so likeβ¦ she's holding onto your BIO now. the relationship is real. be aware π«Ά
π₯ RETURN VALUES π₯
- On success:
OSSL_STORE_attach()returns a pointer to anOSSL_STORE_CTX. slay β¨ - On failure: it returns
NULL. it's giving "not today" π
π SEE ALSO π
go read those too, iykyk π
π HISTORY π

okay and for the little sign-off situation: this page is from OpenSSL 4.0.3, dated 2026-09-29, and she lives under the name OSSL_STORE_ATTACH(3SSL). periodt πβ¨π¦ go attach some BIOs bestie, you're gonna do great π«ΆπΈ
