Extended attributes are name:value pairs associated with inodes
(files, directories, symbolic links, 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 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 removexattr(), only the extended
attribute is removed from the open file referred to by fd (as returned
by open(2)
) in place of 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.
On success,
zero is returned. On failure, -1 is returned and errno is set appropriately.
- ENOATTR
- The named attribute does not exist. (ENOATTR is defined to
be a synonym for ENODATA in <attr/xattr.h>.)
- ENOTSUP
- Extended attributes are
not supported by the filesystem, or are disabled.
In addition, the errors
documented in stat(2)
can also occur.
These system calls have been
available on Linux since kernel 2.4; glibc support is provided since version
2.3.
These system calls are Linux-specific.
