SYNOPSIS

DESCRIPTION

15       Handles have a name which is unique within the current process.  The
16       handle name is used in debug output.
17
18       Handle names are normally generated automatically and have the form
19       "nbd1", "nbd2", etc., but you can optionally use this call to give the
20       handles a name which is meaningful for your application to make
21       debugging output easier to understand.
22

RETURN VALUE

24       If the call is successful the function returns 0.
25

ERRORS
