/* NAME
/*	tls_proxy_client_misc 3
/* SUMMARY
/*	TLS_CLIENT_XXX structure support
/* SYNOPSIS
/*	#include <tls_proxy.h>
/*
/*	TLS_CLIENT_PARAMS *tls_proxy_client_param_from_config(params)
/*	TLS_CLIENT_PARAMS *params;

/* 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.
