/* 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;

/* 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), ...
