removexattr, lremovexattr, fremovexattr - remove an extended attribute
Standard C library (libc
, -lc
)
#include <sys/xattr.h>
int removexattr(const char *path, const char *name);
int lremovexattr(const char *path, const char *name);
int fremovexattr(int fd, const char *name);
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
xattr(7).
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 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 to indicate the error.
The named attribute does not exist.
Extended attributes are not supported by the filesystem, or are disabled.
In addition, the errors documented in stat(2) can also occur.
