+/* 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.
