41 This vnode call may be used to determine the validity of a particular access
42 control list (ACL) for a particular file or directory.
47 the vnode of the file or directory
49 the type of ACL to check
51 a pointer to an ACL structure from which to retrieve the ACL data
53 the user credentials to use in authorizing the request
55 the process checking the ACL
60 pointer may be NULL to indicate that access control checks are not to be
61 performed, if possible. This cred setting might be used to allow the
62 kernel to authorize ACL verification that the active process might not be
65 The vnode ACL interface defines the syntax, and not semantics, of file and
66 directory ACL interfaces. More information about ACL management in kernel
70 No locks are required to call this vnode method, and any locks held on
71 entry will be held on exit.
75 pointer points to a valid ACL of type
79 then zero is returned. Otherwise, an appropriate error code is returned.
83 The ACL type passed is invalid for this vnode, or the ACL data is invalid
87 Insufficient memory available to fulfill request
89 The file system does not support VOP_ACLCHECK
