SYNOPSIS
.In sys/param.h
.In sys/mount.h
.In sys/vnode.h int VFS_FHTOVP "struct mount *mp" "struct fid *fhp" "struct vnode **vpp"
DESCRIPTION
The VFS_FHTOVP macro is used by the NFS server to turn an NFS filehandle into a vnode. The arguments it expects are: | mp | The file system. | | fhp | The filehandle to convert. | | vpp | Return parameter for the new locked vnode. | |
The contents of the filehandle are defined by the file system and are not examined by any other part of the system. It should contain enough information to uniquely identify a file within the file system as well as noticing when a file has been removed and the file system resources have been reused for a new file. For instance, UFS file system stores the inode number and inode generation counter in its filehandle. A call to VFS_FHTOVP should generally be preceded by a call to VFS_CHECKEXP(9) to check if the file is accessible to the client.
RETURN VALUES
The locked vnode for the file will be returned in *vpp.
