Hi,

Currently I am doing a small project on OpenAFS. Now, I am planning to read
the Vnode associated with a file. My idea is let user enter the command 'fs
getvnode FILE_NAME'
to view the vnode (status) information:
(1) user enters 'fs getvnode /afs'
(2) first get the fid for that file and then use the fid to get the vnode

while for (1) response is in the file /venus/fs.c, the function to get
vnode is implemented in file /vol/vnode.c. I want to call the VGetVnode()
in fs.c. But
I always failed to make the modified codes. Error is:
/openafs-1.4.14/lib/vlib.a(volume.o): In function 'VReleaseVolumeHandles_r':
/openafs-1.4.14/src/vol/volume.c: 1235: undefined reference to
'DFlushVolume'
/openafs-1.4.14/lib/vlib.a(volume.o): In function 'VCloseVolumeHandles_r':
/openafs-1.4.14/src/vol/volume.c: 1323: undefined reference to
'DFlushVolume'

My modifications are:
(1) include more headers:
#include <afs/ihandle.h>
#include <afs/nfs.h>
#include <afs/vnode.h>
#include <afs/volume.h>
#include <afs/dir.h>

(2) within the method GetFidCmd() I added two lines with the if(0 ==
pioctl(ti->data, VIOCGETFID, &blob, 1))
int errorCode;
Volume * vol = VGetVolume(&errorCode, (afs_int32)vfid.Fid.Volume);

I didn't change the Makefile since seems no need to change that.

I am a newbie to OpenAFS and C, plz help me to solve this silly question.
Or, better idea to achieve this?

Regards,
