+/* NAME
+/*	dsb_scan
+/* SUMMARY
+/*	read DSN_BUF from stream
+/* SYNOPSIS
+/*	#include <dsb_scan.h>
+/*
+/*	int	dsb_scan(scan_fn, stream, flags, ptr)
+/*	ATTR_SCAN_MASTER_FN scan_fn;
+/*	VSTREAM *stream;
+/*	int	flags;
+/*	void	*ptr;
+/* DESCRIPTION
+/*	dsb_scan() reads a DSN_BUF from the named stream using the
+/*	specified attribute scan routine. dsb_scan() is meant
+/*	to be passed as a call-back to attr_scan(), thusly:
+/*
+/*	... RECV_ATTR_FUNC(dsb_scan, (void *) &dsbuf), ...
+/* DIAGNOSTICS
+/*	Fatal: out of memory.
