VOP_SETACL(9)              Kernel Developer's Manual             VOP_SETACL(9)

     VOP_SETACL - set the access control list for a vnode

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

     VOP_SETACL(struct vnode *vp, acl_type_t type, struct acl *aclp,
         kauth_cred_t cred);

     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.

     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.

     [EACCES]           The caller does not have the appropriate privilege.

     [EINVAL]           The ACL type passed is invalid for this vnode, or the
                        ACL data is invalid.

     [ENOMEM]           Sufficient memory is not available to fulfill the

     [ENOSPC]           The file system is out of space.

     [EOPNOTSUPP]       The file system does not support VOP_SETACL().

     [EROFS]            The file system is read-only.
