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