DESCRIPTION
The
Fn acl_set_fd

ERRORS
If any of the following conditions occur, the
Fn acl_set_fd
function returns the value
-1
and and sets
errno
to the corresponding value:
- Bq Er EBADF
-
The
fd
argument is not a valid file descriptor.
- Bq Er EINVAL
-
The argument
acl
does not point to a valid ACL.
The ACL has more entries than the file referred to by
fd
can obtain.
- Bq Er ENOSPC
-
The directory or file system that would contain the new ACL cannot be extended or the file system is out of file allocation resources.
- Bq Er ENOTSUP
-
The file identified by
fd
cannot be associated with the ACL because the file system on which the file
is located does not support this.
- Bq Er EPERM
-
The process does not have appropriate privilege to perform the operation to set the ACL.
- Bq Er EROFS
-
This function requires modification of a file system which is currently read-only.
