NAME

acl_delete_def_file acl_delete_def_file_at - delete a default ACL by filename  

LIBRARY

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

SYNOPSIS

In sys/types.h In sys/acl.h Ft int Fo acl_delete_def_file Fa const char *path_p Fc Ft int Fo acl_delete_def_file_at Fa int dirfd Fa const char *path_p Fa int at_flags Fc  

DESCRIPTION

The Fn acl_delete_def_file function deletes a default ACL from the directory whose pathname is given in path_p If path_p is a symbolic link, Fn acl_delete_def_file operates on the directory the link refers to.

The effective user ID of the process must match the owner of the file or directory or the process must have the CAP_FOWNER capability for the request to succeed.

If the argument path_p is not a directory, then the function fails. It is no error if the directory whose pathname is pointed to by the argument path_p does not have a default ACL.  

Fn acl_delete_def_file_at

The Fn acl_delete_def_file_at function operates in exactly the same way as Fn acl_delete_def_file , except for the differences described here.

If the pathname given in path_p is relative, then it is interpreted relative to the directory referred to by the file descriptor dirfd (rather than relative to the current working directory of the calling process, as is done by Fn acl_delete_def_file ) .

If path_p is relative and dirfd is the special value AT_FDCWD then path_p is interpreted relative to the current working directory of the calling process (like Fn acl_delete_def_file ) .

If path_p is absolute, then dirfd is ignored.

The at_flags argument can either be 0, or include one or more of the following flags ORed:

AT_EMPTY_PATH

If path_p is an empty string, operate on the file referred to by dirfd (which may have been obtained using the open(2) O_PATH flag). In this case, dirfd can refer to any type of file, not just a directory.

AT_SYMLINK_NOFOLLOW

If path_p refers to a symbolic link, do not dereference it: instead, fail the operation and set the global variable errno to Er ENOTSUP . This indicates that the symbolic link cannot have ACLs.

 

RETURN VALUE

Rv -std acl_delete_def_file acl_delete_def_file_at  

ERRORS

If any of the following conditions occur, the Fn acl_delete_def_file and Fn acl_delete_def_file_at functions return the value -1 and set errno to the corresponding value:

Bq Er EBADF

The argument path_p is relative but the argument dirfd is neither AT_FDCWD nor a valid file descriptor.

Bq Er EINVAL

The file referred to by path_p is not a directory.

An invalid flag was specified in the at_flags argument.

Bq Er ENOTDIR

A component of the path prefix is not a directory.

The argument path_p is relative and the argument dirfd is a file descriptor referring to a file other than a directory.

Bq Er ENOTSUP

The argument at_flags includes the flag AT_SYMLINK_NOFOLLOW and path_p is a symbolic link.

The file system on which the file identified by path_p is located does not support ACLs, or ACLs are disabled.

Bq Er EPERM

The process does not have appropriate privilege to perform the operation to delete the default ACL.

Bq Er EROFS

This function requires modification of a file system which is currently rea-only.

 

STANDARDS

Function Fn acl_delete_def_file_at is a Linux specific extension.
