23 /* DESCRIPTION
24 /* tls_proxy_client_param_from_config() initializes a TLS_CLIENT_PARAMS
25 /* structure from configuration parameters and returns its
26 /* argument. Strings are not copied. The result must therefore
27 /* not be passed to tls_proxy_client_param_free().
28 /*
29 /* tls_proxy_client_param_serialize() and
30 /* tls_proxy_client_init_serialize() serialize the specified
31 /* object to a memory buffer, using the specified print function
32 /* (typically, attr_print_plain). The result can be used
33 /* determine whether there are any differences between instances
34 /* of the same object type.
