ACL_SET_FD(3) Library Functions Manual ACL_SET_FD(3)
NAME
acl_set_fd — set an ACL by file descriptor
LIBRARY
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
<sys/types.h> <sys/acl.h> 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 succeed.
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 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.
STANDARDS
IEEE Std 1003.1e draft 17 (“POSIX.1e”, abandoned)
