NAME

acl_set_fd - set an ACL by file descriptor

LIBRARY

Linux Access Control Lists library (libacl, -lacl).

SYNOPSIS

In sys/types.h In sys/acl.h Ft int Fn acl_set_fd int fd acl_t acl

DESCRIPTION

The Fn 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.

RETURN VALUE

Rv -std 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.

STANDARDS

IEEE Std 1003.1e draft 17 (lqPOSIX.1erq, abandoned)
