7 /* read DSN_BUF from stream
8 /* SYNOPSIS

11 /* int dsb_scan(scan_fn, stream, flags, ptr)
12 /* ATTR_SCAN_COMMON_FN scan_fn;

16 /* DESCRIPTION
17 /* dsb_scan() reads a DSN_BUF from the named stream using the
18 /* specified attribute scan routine. dsb_scan() is meant
19 /* to be passed as a call-back to attr_scan(), thusly:

22 /* DIAGNOSTICS
23 /* Fatal: out of memory.
