Regarding procfs in freeBSd

[ravi]

Hi,
How to get a pointer to pfs_info structure  which points to the /proc
 directory ?
 
 I mean , I want to create a proc entry under /proc .
 But for this I need to pass an argument struct pfs_info *pi, which
 contains a member pi_root which inturn points to the /proc's pfs_node

 
 How to get this pi_root from pfs_info structure ?
 Is there any global variable which points to /proc' pfs_node .?


That is .. I want to create my own proc entry under /proc . How to do
that ?
