+/*++
+/* NAME
+/* tls_proxy_context_print
+/* SUMMARY
+/* write TLS_ATTR_STATE structure to stream
+/* SYNOPSIS
+/* #include <tls_proxy.h>
+/*
+/* int tls_proxy_context_print(print_fn, stream, flags, ptr)
+/* ATTR_PRINT_MASTER_FN print_fn;
+/* VSTREAM *stream;
+/* int flags;
+/* void *ptr;
+/* DESCRIPTION
+/* tls_proxy_context_print() writes the public members of a
+/* TLS_ATTR_STATE structure to the named stream using the
+/* specified attribute print routine. tls_proxy_context_print()
+/* is meant to be passed as a call-back to attr_print(), thusly:
+/*
+/* ... SEND_ATTR_FUNC(tls_proxy_context_print, (void *) tls_context), ...
+/* DIAGNOSTICS
+/* Fatal: out of memory.
