*
* Most common client applications will not directly interact with
* #GTlsDatabase. It is used internally by #GTlsConnection.

/**
* g_tls_database_verify_chain:
* @self: a #GTlsDatabase
* @chain: a #GTlsCertificate chain
* @purpose: the purpose that this certificate chain will be used for.
* @identity: (nullable): the expected peer identity
* @interaction: (nullable): used to interact with the user if necessary
* @flags: additional verify flags
* @cancellable: (nullable): a #GCancellable, or %NULL
* @error: (nullable): a #GError, or %NULL
*
* Determines the validity of a certificate chain after looking up and
* adding any missing certificates to the chain.
*
* @chain is a chain of #GTlsCertificate objects each pointing to the next
* certificate in the chain by its #GTlsCertificate:issuer property. The chain may initially
* consist of one or more certificates. After the verification process is
* complete, @chain may be modified by adding missing certificates, or removing
* extra certificates. If a certificate anchor was found, then it is added to
* the @chain.
*
* @purpose describes the purpose (or usage) for which the certificate
* is being used. Typically @purpose will be set to #G_TLS_DATABASE_PURPOSE_AUTHENTICATE_SERVER
* which means that the certificate is being used to authenticate a server
* (and we are acting as the client).
*
* The @identity is used to ensure the server certificate is valid for
* the expected peer identity. If the identity does not match the
* certificate, %G_TLS_CERTIFICATE_BAD_IDENTITY will be set in the
* return value. If @identity is %NULL, that bit will never be set in
* the return value. The peer identity may also be used to check for
* pinned certificates (trust exceptions) in the database. These may
* override the normal verification process on a host-by-host basis.
*
* Currently there are no @flags, and %G_TLS_DATABASE_VERIFY_NONE should be
* used.
*
* If @chain is found to be valid, then the return value will be 0. If
* @chain is found to be invalid, then the return value will indicate
* the problems found. If the function is unable to determine whether
* @chain is valid or not (eg, because @cancellable is triggered
* before it completes) then the return value will be
* %G_TLS_CERTIFICATE_GENERIC_ERROR and @error will be set
* accordingly. @error is not set when @chain is successfully analyzed
* but found to be invalid.
*
* This function can block, use g_tls_database_verify_chain_async() to perform
* the verification operation asynchronously.
*
* Returns: the appropriate #GTlsCertificateFlags which represents the
* result of verification.
*
* Since: 2.30
