VOP_GETACL(9) BSD Kernel Developer's Manual VOP_GETACL(9)NAMEVOP_GETACL — retrieve access control list for a vnode
SYNOPSIS
#include <sys/param.h>
#include <sys/vnode.h>
#include <sys/acl.h>
int
VOP_GETACL(struct vnode *vp, acl_type_t type, struct acl *aclp,
struct ucred *cred, struct proc *p);
DESCRIPTION
This vnode call may be used to retrieve the access control list (ACL)
from a file or directory.
Its arguments are:
vp the vnode of the file or directory
type the type of ACL to retrieve
aclp a pointer to an ACL structure to receive the ACL data
cred the user credentials to use in authorizing the request
p the process requesting the ACL
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 retrieval that the active process might
not be permitted to do.
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).
LOCKS
No locks are required to call this vnode method, and any locks held on
entry will be held on exit.
RETURN VALUES
If the aclp pointer will point to a valid ACL, then zero is returned.
Otherwise, an appropriate error code is returned.
ERRORS
[EINVAL] The ACL type passed is invalid for this vnode
[EACCES] Permission denied
[ENOMEM] Insufficient memory available to fulfill request
[EOPNOTSUPP] The file system does not support VOP_GETACL()SEE ALSOacl(9), vnode(9), VOP_ACLCHECK(9), VOP_SETACL(9)AUTHORS
