Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
int
acl_set_fd(int fd, acl_t acl)
DESCRIPTION
The acl_set_fd() function associates an access ACL with the file referred
to by fd.
The effective user ID of the process must match the owner of the file or
the process must have the CAP_FOWNER capability for the request to suc
ceed.
RETURN VALUE
The acl_set_fd() function returns the value 0 if successful; otherwise
the value -1 is returned and the global variable errno is set to indicate
the error.
ERRORS
If any of the following conditions occur, the acl_set_fd() function re
turns the value -1 and and sets errno to the corresponding value:
[EBADF] The fd argument is not a valid file descriptor.
[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.
[ENOSPC] The directory or file system that would contain the new ACL
cannot be extended or the file system is out of file allo
cation resources.
[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.
[EPERM] The process does not have appropriate privilege to perform
the operation to set the ACL.
[EROFS] This function requires modification of a file system which
is currently read-only.
