dm_obj_ref_query prototype in /usr/include/dmapi.h

[Deepak_5]

Hi,

Do any one has any idea about dm_obj_ref_query prototype in /usr/include/dmapi.h.

It says,
extern int dm_obj_ref_query __(dm_sessid_t, dm_token_t, void *, size_t));

How does one use it.
"__( " macro is not defined in the header file, neither
in any header file inclusions is done in this header file.
Got any idea, how it is used.
I guess ,It should be like this one below:
extern int dm_obj_ref_query (dm_sessid_t, dm_token_t, void *, size_t);

Please let me know, if anyone knows about it.

Thanks and Regards
Deepak
