VOP_SETACL -- set the access control list for a vnode
VOP_SETACL(struct vnode *vp, acl_type_t type, struct acl *aclp,
struct ucred *cred, struct thread *td);
This vnode call may be used to set the access control list (ACL) for a
file or directory.
Its arguments are:
vp the vnode of the file or directory
type the type of ACL to set
aclp a pointer to an ACL structure from which to retrieve the ACL data
cred the user credentials to use in authorizing the request
td the thread setting the ACL
The aclp pointer may be NULL to indicate that the specified ACL should be
The cred pointer may be NULL to indicate that access control checks are
not to be performed, if possible. This cred setting might be used to
allow the kernel to authorize ACL changes that the active process might
not be permitted to make.
The vnode ACL interface defines the syntax, and not semantics, of file
and directory ACL interfaces. More information about ACL management in
kernel may be found in acl(9).
The vnode will be locked on entry and should remain locked on return.
If the ACL is successfully set, then zero is returned. Otherwise, an
appropriate error code is returned.
[EINVAL] The ACL type passed is invalid for this vnode, or the
ACL data is invalid.
[EACCES] The the caller does not have the appropriate privilege.
[ENOMEM] Sufficient memory is not available to fulfill the
[EOPNOTSUPP] The file system does not support VOP_SETACL().
[ENOSPC] The file system is out of space.
[EROFS] The file system is read-only.
