NAME



acl_set_fd

 
acl_set_fd_np

 
acl_set_file

 
acl_set_link_np

 - set an ACL for a file

LIBRARY

Lb libc

SYNOPSIS

#include <sys/types.h>
#include <sys/acl.h>
int acl_set_fd (int fd acl_t acl);
int acl_set_fd_np (int fd acl_t acl acl_type_t type);
int acl_set_file (const char *path_p acl_type_t type acl_t acl);
int acl_set_link_np (const char *path_p acl_type_t type acl_t acl);

DESCRIPTION

The acl_set_fd (,);
acl_set_fd_np (,);
acl_set_file (,);
and acl_set_link_np ();
each associate an ACL with an object referred to by fd or path_p The acl_set_fd_np ();
and acl_set_link_np ();
functions are not POSIX.1e calls. The acl_set_fd ();
function allows only the setting of ACLs of type ACL_TYPE_ACCESS where as acl_set_fd_np ();
allows the setting of ACLs of any type. The acl_set_link_np ();
function acts on a symlink rather than its target, if the target of the path is a symlink.

IMPLEMENTATION NOTES

Fx Ns 's support for POSIX.1e interfaces and features is still under development at this time.

RETURN VALUES

Rv -std

ERRORS

If any of the following conditions occur, these functions shall return -1 and set errno to the corresponding value:

Bq Er EACCES: Search permission is denied for a component of the path prefix, or the object exists and the process does not have appropriate access rights.
Bq Er EBADF: The fd argument is not a valid file descriptor.
Bq Er EINVAL: Argument acl does not point to a valid ACL for this object, or the ACL type specified in type is invalid for this object, or both.
Bq Er ENAMETOOLONG: A component of a pathname exceeded 255 characters, or an entire path name exceeded 1023 characters.
Bq Er ENOENT: The named object does not exist, or the path_p argument points to an empty string.
Bq Er ENOMEM: Insufficient memory available to fulfill request.
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 EOPNOTSUPP: The file system does not support ACL retrieval.
Bq Er EROFS: This function requires modification of a file system which is currently read-only.

STANDARDS

POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion of the draft continues on the cross-platform POSIX.1e implementation mailing list. To join this list, see the Fx POSIX.1e implementation page for more information.
