# NAME

OSSL_STORE_attach - Functions to read objects from a BIO

# SYNOPSIS

     #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);

# DESCRIPTION

`OSSL_STORE_attach()` works like OSSL_STORE_open(3), except it takes a BIO bio instead of a uri, along with a scheme to determine what loader should be used to process the data. The reference count of the BIO object is increased by 1 if the call is successful.

# RETURN VALUES

`OSSL_STORE_attach()` returns a pointer to a OSSL_STORE_CTX on success, or NULL on failure.

# SEE ALSO

ossl_store(7), OSSL_STORE_open(3)

# HISTORY

`OSSL_STORE_attach()` was added in OpenSSL 3.0.
