REMOVEXATTR(2) Linux Programmer's Manual REMOVEXATTR(2)
NAME
removexattr, lremovexattr, fremovexattr - remove an extended attribute
SYNOPSIS
#include <sys/types.h>
#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);
DESCRIPTION
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 names-
paces associated with an individual inode.
RETURN VALUE
On success, zero is returned. On failure, -1 is returned and errno is
set appropriately.
ERRORS
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.
VERSIONS
These system calls have been available on Linux since kernel 2.4; glibc
support is provided since version 2.3.
CONFORMING TO
These system calls are Linux-specific.
