Sets the access control list (ACL) for a file.
#include <sys/acl.h>
int vn_setacl (vp, uiop, crp) struct vnode *vp; struct uio *uiop; struct ucred *crp;
vp | Specifies the virtual node (v-node) of the file system object. |
uiop | Specifies the uio structure that defines the storage for the call arguments. |
crp | Points to the cred structure. This structure contains data that the file system can use to validate access permission. |
The vn_setacl entry point is used by the logical file system to set the access control list (ACL) on a file.
The vn_setacl entry point can be called from the process environment only.
0 | Indicates success. |
Nonzero return values are returned from the /usr/include/sys/errno.h file to indicate failure. Valid values include:
The uio structure.
The chacl subroutine, chown subroutine, chmod subroutine, statacl subroutine.
