ACL_SET_FD(3) Library Functions Manual ACL_SET_FD(3)
acl_set_fd — set an ACL by file descriptor
Linux Access Control Lists library (libacl, -lacl).
<sys/types.h> <sys/acl.h> int acl_set_fd(int fd, acl_t acl)
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 succeed.
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.
If any of the following conditions occur, the acl_set_fd()
function returns 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 allocation 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.
