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
file system.
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.
If the named attribute does not exist, errno is set to ENOATTR.
If extended attributes are not supported by the file
system, or are disabled, errno
is set to ENOTSUP.
The errors documented for the stat(2) system call are also applicable here.
These system calls have been available on Linux since kernel 2.4; glibc support is provided since version 2.3.
