VOP_ATTRIB(9)

VOP_ATTRIB(9)            BSD Kernel Developer's Manual           VOP_ATTRIB(9)

NAME
     VOP_GETATTR, VOP_SETATTR — get and set attributes on a file or directory

SYNOPSIS
     #include <sys/param.h>
     #include <sys/vnode.h>

     int
     VOP_GETATTR(struct vnode *vp, struct vattr *vap, struct ucred *cred);

     int
     VOP_SETATTR(struct vnode *vp, struct vattr *vap, struct ucred *cred);

DESCRIPTION
     These entry points manipulate various attributes of a file or directory,
     including file permissions, owner, group, size, access time and modifica‐
     tion time.

     The arguments are:

     vp    The vnode of the file.

     vap   The attributes of the file.

     cred  The user credentials of the calling process.

     Attributes which are not being modified by VOP_SETATTR() should be set to
     the value VNOVAL; VATTR_NULL() may be used to clear all the values, and
     should generally be used to reset the contents of *vap prior to setting
     specific values.

LOCKS
     VOP_GETATTR() expects the vnode to be locked on entry and will leave the
     vnode locked on return.  The lock type can be either shared or exclusive.

     VOP_SETATTR() expects the vnode to be locked on entry and will leave the
     vnode locked on return.  The lock type must be exclusive.

RETURN VALUES
     VOP_GETATTR() returns 0 if it was able to retrieve the attribute data via
     *vap, otherwise an appropriate error is returned.  VOP_SETATTR() returns
     zero if the attributes were changed successfully, otherwise an appropri‐
     ate error is returned.

ERRORS
     [EPERM]            The file is immutable.

     [EACCES]           The caller does not have permission to modify the file
                        or directory attributes.

     [EROFS]            The file system is read-only.
