=head1 NAME

OSSL_STORE_attach - Functions to read objects from a BIO

=head1 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);

=head1 DESCRIPTION

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

=head1 RETURN VALUES

OSSL_STORE_attach() returns a pointer to a B<OSSL_STORE_CTX> on success, or
NULL on failure.

=head1 SEE ALSO

L<ossl_store(7)>, L<OSSL_STORE_open(3)>

=head1 HISTORY

OSSL_STORE_attach() was added in OpenSSL 3.0.
