Re: Current Directory of a Process

I can get the vnode pointing to the current directory, and that is good... Sort of. I need to be able to translate this vnode to a path name to be used in user space. I have poured through the kernel and not found a way to do that. In desperation I downloaded the code for Libc and looked at the getcwd code. Horror! If you want to spend some sleepless nights having nightmares look at Libc/gen/getcwd.c. Obviously that type of solution is not practical for the kernel.

Any ideas how to translate a vnode to a path? Or any other ideas how to get the current directory?

Thanks

I have a struct proc * inside a sysent[xxx] call and from there want to get the current working directory of the process that initiated the action. I have looked through the kernel and the mailing list archives and not found any obvious pointers.

Does anybody have any ideas?

You can look at xnu/bsd/vfs/vfs_syscalls:chdir() to see how the various structures are stitched together. Is this what you are looking for?
