NAME
attr_remove, attr_removef - remove a user attribute of a filesystem object
C SYNOPSIS
#include <attr/attributes.h>int attr_remove (const char *path, const char *attrname, int flags);int attr_removef (int fd, const char *attrname, int flags);
[
DESCRIPTION
]
The
attr_remove
and
attr_removef
functions provide a way to remove previously created attributes
from filesystem objects.
Path
points to a path name for a filesystem object, and
fd
refers to the file descriptor associated with a file.
If the attribute
attrname
exists, the attribute name and value will be removed from the
fileystem object.
The
flags
argument can contain the following symbols bitwise OR'ed together:
ATTR_ROOT
Look for
attrname
in the
root
address space, not in the
user
address space.
(limited to use by super-user only)
ATTR_DONTFOLLOW
Do not follow symbolic links when resolving a
path
on an
attr_remove
function call.
The default is to follow symbolic links.
attr_remove
will fail if one or more of the following are true:
[ENOATTR]
The attribute name given is not associated with the indicated
filesystem object.
[ENOENT]
The named file does not exist.
[EPERM]
The effective user
ID
does not match the owner of the file
and the effective user
ID
is not super-user.
[ENOTDIR]
A component of the
path prefix
is not a directory.
[EACCES]
Search permission is denied on a
component of the
path prefix.
[EINVAL]
A bit was set in the
flag
argument that is not defined for this system call.
[EFAULT]
Path
points outside the allocated address space of the process.
[ELOOP]
A path name lookup involved too many symbolic links.
[ENAMETOOLONG]
The length of
path
exceeds
{MAXPATHLEN},
or a pathname component is longer than
{MAXNAMELEN}.
attr_removef
will fail if:
[ENOATTR]
The attribute name given is not associated with the indicated
filesystem object.
[EINVAL]
A bit was set in the
flag
argument that is not defined for this system call,
or
fd
refers to a socket, not a file.
[EFAULT]
Attrname
points outside the allocated address space of the process.
[EBADF]
Fd
does not refer to a valid descriptor.
DIAGNOSTICS
On success, zero is returned. On error, -1 is returned, and
errno
is set appropriately.
