=head1 SYNOPSIS

 #include <openssl/ssl.h>

 int SSL_CTX_set0_verify_cert_store(SSL_CTX *ctx, X509_STORE *st);
 int SSL_CTX_set1_verify_cert_store(SSL_CTX *ctx, X509_STORE *st);
 int SSL_CTX_set0_chain_cert_store(SSL_CTX *ctx, X509_STORE *st);
 int SSL_CTX_set1_chain_cert_store(SSL_CTX *ctx, X509_STORE *st);

 int SSL_set0_verify_cert_store(SSL *ctx, X509_STORE *st);
 int SSL_set1_verify_cert_store(SSL *ctx, X509_STORE *st);
 int SSL_set0_chain_cert_store(SSL *ctx, X509_STORE *st);
 int SSL_set1_chain_cert_store(SSL *ctx, X509_STORE *st);

=head1 DESCRIPTION

SSL_CTX_set0_verify_cert_store() and SSL_CTX_set1_verify_cert_store()
set the certificate store used for certificate verification to B<st>.

SSL_CTX_set0_chain_cert_store() and SSL_CTX_set1_chain_cert_store()
set the certificate store used for certificate chain building to B<st>.

SSL_set0_verify_cert_store(), SSL_set1_verify_cert_store(),
SSL_set0_chain_cert_store() and SSL_set1_chain_cert_store() are similar
except they apply to SSL structure B<ssl>.

All these functions are implemented as macros. Those containing a B<1>
increment the reference count of the supplied store so it must
be freed at some point after the operation. Those containing a B<0> do
not increment reference counts and the supplied store B<MUST NOT> be freed
after the operation.

=head1 NOTES

The stores pointers associated with an SSL_CTX structure are copied to any SSL
structures when SSL_new() is called. As a result SSL structures will not be
affected if the parent SSL_CTX store pointer is set to a new value.

The verification store is used to verify the certificate chain sent by the
peer: that is an SSL/TLS client will use the verification store to verify
the server's certificate chain and a SSL/TLS server will use it to verify
any client certificate chain.

The chain store is used to build the certificate chain.

If the mode B<SSL_MODE_NO_AUTO_CHAIN> is set or a certificate chain is
configured already (for example using the functions such as
L<SSL_CTX_add1_chain_cert(3)> or
L<SSL_CTX_add_extra_chain_cert(3)>) then
automatic chain building is disabled.

If the mode B<SSL_MODE_NO_AUTO_CHAIN> is set then automatic chain building
is disabled.

If the chain or the verification store is not set then the store associated
with the parent SSL_CTX is used instead to retain compatibility with previous
versions of OpenSSL.

=head1 RETURN VALUES

All these functions return 1 for success and 0 for failure.
