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