REMOVEXATTR
NAME
removexattr, lremovexattr, fremovexattr - remove an extended attribute
SYNOPSIS
#include <sys/types.h>
#include <attr/xattr.h>
I int removexattr (const char * path , const char * name );
I int lremovexattr (const char * path , const char * name );
I int fremovexattr (int filedes , const char * name );
DESCRIPTION
Extended attributes are
R name :\c
value pairs associated with inodes (files, directories, symlinks, etc).
They are extensions to the normal attributes which are associated
with all inodes in the system (i.e. the
stat(2)
data).
A complete overview of extended attributes concepts can be found in
attr(5).
removexattr
removes the extended attribute identified by
name
and associated with the given
path
in the filesystem.
lremovexattr
is identical to
R removexattr ,
except in the case of a symbolic link, where the extended attribute is
removed from the link itself, not the file that it refers to.
fremovexattr
is identical to
R removexattr ,
only the extended attribute is removed from the open file pointed to by
filedes
(as returned by
open(2))
in place of
R path .
An extended attribute name is a simple NULL-terminated string.
The
name
includes a namespace prefix - there may be several, disjoint
namespaces associated with an individual inode.
RETURN VALUE
On success, zero is returned.
On failure, -1 is returned and
errno
is set appropriately.
If the named attribute does not exist,
errno
is set to ENOATTR.
If extended attributes are not supported by the filesystem, or are disabled,
errno
is set to ENOTSUP.
The errors documented for the
stat(2)
system call are also applicable here.
