ACL_DELETE(3)           NetBSD Library Functions Manual          ACL_DELETE(3)


NAME

     acl_delete_def_file, acl_delete_def_link_np, acl_delete_fd_np,
     acl_delete_file_np, acl_delete_link_np -- delete an ACL from a file


LIBRARY

     Standard C Library (libc, -lc)


SYNOPSIS

     #include <sys/types.h>
     #include <sys/acl.h>

     int
     acl_delete_def_file(const char *path_p);

     int
     acl_delete_def_link_np(const char *path_p);

     int
     acl_delete_fd_np(int filedes, acl_type_t type);

     int
     acl_delete_file_np(const char *path_p, acl_type_t type);

     int
     acl_delete_link_np(const char *path_p, acl_type_t type);


DESCRIPTION

     The acl_delete_def_file(), acl_delete_def_link_np(), acl_delete_fd_np(),
     acl_delete_file_np(), and acl_delete_link_np() each allow the deletion of
     an ACL from a file.  The acl_delete_def_file() function is a POSIX.1e
     call that deletes the default ACL from a file (normally a directory) by
     name; the remainder of the calls are non-portable extensions that permit
     the deletion of arbitrary ACL types from a file/directory either by path
     name or file descriptor.  The _file() variations follow a symlink if it
     occurs in the last segment of the path name; the _link() variations oper-
     ate on the symlink itself.


IMPLEMENTATION NOTES

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


RETURN VALUES

     Upon successful completion, the value 0 is returned; 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, these functions shall return -1
     and set errno to the corresponding value:

     [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.

     [EBADF]            The fd argument is not a valid file descriptor.

     [EINVAL]           The ACL type passed is invalid for this file object.

     [ENAMETOOLONG]     A component of a pathname exceeded 255 characters, or
                        an entire path name exceeded 1023 characters.

     [ENOENT]           The named object does not exist, or the path_p argu-
                        ment points to an empty string.

     [ENOMEM]           Insufficient memory available to fulfill request.

     [ENOTDIR]          A component of the path prefix is not a directory.

                        Argument path_p must be a directory, and is not.

     [EOPNOTSUPP]       The file system does not support ACL deletion.

     [EPERM]            The process does not have appropriate privilege to
                        perform the operation to delete an ACL.

     [EROFS]            The file system is 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 FreeBSD POSIX.1e implementation page for more
     information.


HISTORY

     POSIX.1e support was introduced in FreeBSD 4.0, and development contin-
     ues.
